[0024] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0025] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0026] The following is a detailed description of the assembly method of the optical system provided by the embodiment of the present application through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0027] The assembly method of the embodiment of the present application can be applied to Figure 1In the optical system shown, the optical system includes a workbench 1, a first optical lens 2, a second optical lens 3, a laser interferometer 4, and a reflector 5. Generally speaking, the positions of the reflector 5 and the laser interferometer 4 are fixed, and the first optical lens 2 and the second optical lens 3 are arranged between the reflector 5 and the laser interferometer 4. The optical performance of the optical system is determined by the position of the first optical lens 2 in the optical system and the position of the second optical lens 3 in the optical system. The laser interferometer 4 can perform surface shape detection on the lens group formed by the first optical lens 2 and the second optical lens 3.

[0028] The workbench 1 can be an air-floating platform, which generates an air-floating effect between the optical element and the platform by applying pressurized gas on the platform, thereby achieving high-precision translation, rotation and positioning. This platform consists of a platform body and a gas regulating system. The gas regulating system controls the motion state of the air-floating platform by adjusting the air pressure, so that the optical element on the platform maintains a stable motion trajectory. The air-floating platform has millimeter-level translation and rotation accuracy, and has high stability and repeatability. It can be understood that the posture of the first optical lens 2 and the second optical lens 3 can be adjusted by the air-floating platform.

[0029] like Figure 2 As shown, the assembly method of the optical system of the embodiment of the present application specifically includes the following steps:

[0030] Step 101, obtaining the first position information of the first optical lens relative to the laser interferometer.

[0031] In this step, the second optical lens has not been installed in the optical system, and the first optical lens is set at any position between the laser interferometer and the reflector. Since the position of the laser interferometer is generally fixed, obtaining the first position information of the first optical lens relative to the laser interferometer means obtaining the position information of the first optical lens in the entire optical system. For example, taking the light source of the laser interferometer as the origin, a spatial coordinate system is established, and the positions of other components in the optical system can be determined relative to the laser interferometer.

[0032] Step 102: adjust the posture of the first optical lens based on the first posture information.

[0033] In this step, since the first optical lens can be installed at any position between the laser interferometer and the reflector during initial installation, the initial position of the first optical lens may not necessarily meet the performance requirements of the optical system, and the initial position of the first optical lens needs to be adjusted. In this embodiment, the first optical lens or the second optical lens can move in six degrees of freedom relative to the laser interferometer to achieve the purpose of adjusting the position; the six degrees of freedom are the degrees of freedom of movement along the three rectangular coordinate axes of x, y, and z in space, and the degrees of freedom of rotation around the above three coordinate axes.

[0034] Step 103, when the first optical lens is adjusted to be coaxial with the laser interferometer, determining the installation position of the second optical lens.

[0035] After adjusting the posture of the first optical lens in step 102 until the first optical lens is coaxial with the laser interferometer, the installation position of the first optical lens can be determined, wherein the coaxiality of the first optical lens and the laser interferometer is actually manifested as the coaxiality of the first optical lens and the optical axis of the laser interferometer. Since the optical performance of the optical system is determined by the posture of the first optical lens and the second optical lens in the optical system, after the posture of the first optical lens remains unchanged, the posture of the second optical lens that meets the optical performance can be determined based on the posture of the first optical lens. It should be noted that in this step, the exact posture of the second optical lens is still unknown. Generally speaking, the installation position of the second optical lens is between the first optical lens and the laser interferometer. Therefore, the initial position of the second optical lens can be any position between the first optical lens and the laser interferometer, and the inclination angle and eccentricity angle of the second optical lens relative to the laser interferometer are still unknown.

[0036] Step 104: When the second optical lens is installed between the reflector and the laser interferometer, the posture of the second optical lens is adjusted until the surface shape of the lens group formed by the first optical lens and the second optical lens meets the preset surface shape requirement.

[0037] In this step, the initial position and posture of the second optical lens is adjusted until the surface shape of the lens group formed by the first optical lens and the second optical lens meets the preset surface shape requirements. It should be noted that when the surface shape of the lens group formed by the first optical lens and the second optical lens meets the preset surface shape requirements, it means that the position and posture of the lens group can meet the performance requirements of the optical system.

[0038] The assembly method of the optical system provided in the embodiment of the present application includes: obtaining the first position information of the first optical lens relative to the laser interferometer; adjusting the position of the first optical lens based on the first position information; determining the installation position of the second optical lens when the first optical lens is adjusted to be coaxial with the laser interferometer; and adjusting the position of the second optical lens when the second optical lens is installed between the reflector and the laser interferometer until the surface shape of the lens group formed by the first optical lens and the second optical lens meets the preset surface shape requirements. In the above process, the position of the first optical lens in the optical system can be determined first by the condition that the first optical lens and the laser interferometer are coaxial, the position of the first optical lens remains unchanged, and the optical performance of the optical system is determined by the position of the second optical lens. When the surface shape of the lens group formed by the first optical lens and the second optical lens needs to meet the preset surface shape requirements, it means that the performance of the optical system meets the requirements, which also means that the position of the first optical lens and the position of the second optical lens are accurate at this time. Therefore, the assembly accuracy of the optical system can be improved by the above method.

[0039] Optionally, the first posture information includes: an eccentricity angle and a tilt angle;

[0040] The adjusting the posture of the first optical lens based on the first posture information includes:

[0041] Acquire a first preset angle and a second preset angle;

[0042] Determining an adjustment parameter based on the first posture information, the first preset angle, and the second preset angle;

[0043] The position and posture of the first optical lens are adjusted based on the adjustment parameters, and the eccentricity angle of the adjusted first optical lens relative to the laser interferometer is smaller than the first preset angle, and the inclination angle of the adjusted first optical lens relative to the laser interferometer is smaller than the second preset angle.

[0044] In this embodiment, the first posture information includes the eccentricity angle and the tilt angle. Taking the xyz spatial coordinate system as an example, the optical axis direction of the laser interferometer is the x direction, the direction perpendicular to the optical axis direction and in the horizontal plane is the y direction, and the direction perpendicular to the xy horizontal plane is the z direction. The eccentricity angle is "the deviation angle of the line between the center of curvature of the first optical lens and the light source of the laser interferometer relative to the optical axis of the laser interferometer in the y direction", and the tilt angle is "the deviation angle of the line between the center of curvature of the first optical lens and the light source of the laser interferometer relative to the optical axis of the laser interferometer in the z direction".

[0045] The first preset angle and the second preset angle can be understood as a reasonable error range. When the posture of the first optical lens is adjusted to "the eccentric angle of the first optical lens relative to the laser interferometer is less than the first preset angle, and the inclination angle of the first optical lens relative to the laser interferometer is less than the second preset angle", it means that the first optical lens is coaxial with the laser interferometer. The first preset angle and the second preset angle can be the same or different, and the size of the first preset angle and the second preset angle is related to the spacing distance of the first optical lens relative to the laser interferometer. It can be understood that when the posture of the first optical lens remains unchanged, the inclination angle and eccentricity angle of the first optical lens relative to the laser interferometer will also change with the change of the spacing distance. In this embodiment, it is only necessary to adjust the eccentricity angle and inclination angle of the first optical lens relative to the laser interferometer without adjusting the positions on the six degrees of freedom, which reduces the adjustment steps required for the assembly process and can improve the assembly efficiency to a certain extent.

[0046] Optionally, the adjusting the posture of the second optical lens until the surface shape of the lens group formed by the first optical lens and the second optical lens meets a preset surface shape requirement includes:

[0047] Detecting the current clarity of the interference image formed by the mirror group and the laser interferometer;

[0048] Performing a first adjustment on the posture of the second optical lens based on the current clarity, until the clarity of the interference image formed by the lens group and the laser interferometer after the first adjustment meets a preset clarity;

[0049] Detecting a first surface parameter of the mirror assembly;

[0050] A second adjustment is performed on the posture of the second optical lens based on the first surface shape parameters, until the surface shape parameters of the lens group meet preset surface shape parameters after the second adjustment.

[0051] In this embodiment, after determining the position and posture of the first optical lens, the second optical lens is installed on the Guangxu system, and the first optical lens and the second optical lens form a lens group. By detecting the lens group through a laser interferometer, an interference image can be obtained, and the information of the interference image can be collected to obtain the current clarity of the interference image, that is, the interference image is analyzed by quantitative parameters. The clarity of the interference image is "the ratio of the first parameter to the second parameter of the interference image", the first parameter is the difference between the maximum light intensity value and the minimum light intensity value of the interference image, and the second parameter is the sum of the maximum light intensity value and the minimum light intensity value. When the absolute value of the difference between the clarity of the interference image formed by the lens group and the laser interferometer after the first adjustment and the preset clarity is less than a preset threshold, it is explained that the clarity of the interference image meets the preset clarity.

[0052] After the first adjustment process, a second adjustment is performed according to the surface shape parameters of the lens assembly and the preset surface shape parameters, so that the absolute value between the adjusted surface shape parameters of the lens assembly and the preset surface shape parameters is less than a preset threshold. It should be emphasized that the first adjustment and the second adjustment are both aimed at the posture of the second optical lens.

[0053] In this embodiment, after determining the coaxial posture of the first optical lens and the laser interferometer, the posture of the first optical lens is maintained, and it is only necessary to adjust the posture of the second optical lens according to the surface parameters of the lens group and the interference image. There is no need to adjust the two lenses at the same time, which simplifies the process of adjusting the optical lenses and further improves the assembly efficiency.

[0054] Optionally, after performing a second adjustment on the posture of the second optical lens based on the first surface shape parameter until the surface shape parameter of the lens assembly meets the preset surface shape parameter after the second adjustment, the method further includes:

[0055] Under the condition that the first optical lens and the second optical lens are fixed, detecting the second surface parameter of the lens assembly;

[0056] The preload force for fixing the first optical lens and the second optical lens is adjusted based on the second surface shape parameter until the surface shape parameter of the lens assembly meets the preset surface shape parameter.

[0057] In order to ensure the stability of the optical system, the first optical lens and the second optical lens need to be fixed. In this embodiment, considering the influence of the fixed pre-tightening force on the surface shape of the lens group, after the first optical lens and the second optical lens are initially fixed, the surface shape parameters of the lens group are detected again, and the pre-tightening force of the lens group is adjusted so that the surface shape parameters of the lens group meet the preset surface shape parameters, thereby further improving the assembly accuracy.

[0058] Optionally, the first adjustment includes at least one of the following:

[0059] Adjusting the spacing distance between the second optical lens and the first optical lens;

[0060] Adjusting the tilt angle of the second optical lens relative to the laser interferometer;

[0061] Adjust the eccentricity angle of the second optical lens relative to the laser interferometer.

[0062] During the first adjustment process, the second optical lens does not need to consider the movement in all six degrees of freedom. It only needs to adjust the spacing distance relative to the first optical lens and the inclination angle and eccentricity angle relative to the laser interferometer to achieve higher precision assembly, which simplifies the assembly process to a certain extent.

[0063] Optionally, the second adjustment includes at least one of the following:

[0064] Adjusting the spacing distance between the second optical lens and the laser interferometer;

[0065] Adjusting the tilt angle of the second optical lens relative to the laser interferometer;

[0066] Adjust the eccentricity angle of the second optical lens relative to the laser interferometer.

[0067] In this embodiment, similar to the first adjustment process, the second optical lens does not need to consider the movement in all six degrees of freedom, but only needs to adjust the spacing distance, tilt angle and eccentricity angle relative to the laser interferometer to achieve higher precision assembly, which simplifies the assembly process to a certain extent.
