[0038] Hereinafter, the present disclosure will be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the present disclosure are shown. However, the present disclosure can be implemented in different embodiments and should not be construed as being limited to the embodiments described herein.

[0039] This application primarily aims to provide a novel collimator with adjustable slit width, enabling its use in confined spaces. Furthermore, the collimator can be adjusted with multiple degrees of freedom in conjunction with an optical machine, ultimately achieving linear adjustment of the optical machine, collimator, and detector.

Furthermore, the collimator can be rotated and adjusted at a small angle, such as to achieve fine-tuning of deflection in the vertical direction. Finally, the optical machine including this collimator assembly can more accurately achieve linear adjustment of the optical machine, collimator, and detector by adjusting the tube base in two directions.

[0042] As shown in Figures 1 to 5, in an embodiment of the present application, the collimator assembly 1 includes: at least one position adjustment portion 11, the at least one position adjustment portion 11 is located at the end of the collimator assembly 1, and is used to adjust the position of the collimator assembly 1; a collimator body portion 12, the at least one position adjustment portion 11 is located on the collimator body portion 12, and the collimator body portion 12 includes a first adjustment member 121, a left collimator member 122, a right collimator member 123, and a collimator member 124 located on the left collimator member 12. 2 and the adjustment hole 124 on the right collimator component 123, the left collimator component 122 and the right collimator component 123 are arranged side by side and have a collimator slit 125 therebetween, and the adjustment member passes through the corresponding adjustment hole 124 to adjust the width of the collimator slit 125; a shielding box 13, the shielding box 13 is fixed to the collimator main body 12, located on the side opposite to the position adjustment part 11, and has gaps 131 corresponding to the collimator slit 125 at the top and bottom of the shielding box 13.

[0043] In one embodiment of the present application, as shown in Figures 2 and 3, the collimator is composed of multiple components. For example, the collimator includes a position adjustment portion 11, a collimator body portion 12, and a shielding box 13. The collimator body portion 12 includes a first adjustment member 121, a left collimator member 122, a right collimator member 123, and a plurality of adjustment holes 124 located on the left collimator member 122 and the right collimator member 123. The first adjustment member 121 can be a screw, a bolt, or a screw. A collimator slit 125 is provided between the left collimator component 122 and the right collimator component 123. By adjusting the screws respectively located on the left collimator component 122 and the right collimator component 123, the positions of the left collimator component 122 and the right collimator component 123 relative to each other are adjusted, thereby adjusting the distance between the left collimator component 122 and the right collimator component 123, that is, adjusting the width of the collimator slit 125 so that the collimator slit width is within the range of 0.6 mm-1.2 mm.

[0044] In one embodiment of the present application, as shown in Figures 4 and 5, the collimator component may include one or more position adjustment parts 11 for moving the collimator assembly 1 in one direction. Each position adjustment part 11 includes a boss portion 111, and the boss portion 111 is provided with a through hole 112 inside the portion thereof protruding from other parts of the collimator, and at least a section of the inner surface of the through hole 112 is provided with a thread 1121. Providing a section of thread instead of the entire thread can reduce the amount of processing, and at the same time, the threaded engagement portion is not too long, which is convenient for assembly and adjustment. Or in other embodiments, threads are provided on the entire inner surface of the through hole 112.

[0045] In one embodiment of the present application, as shown in Figures 2 to 5, the collimator assembly 1 may include two position adjustment parts 11, each of which includes a boss part 111. In other words, the collimator assembly 1 may include a boss part 111 at each end, which is used to make the collimator assembly 1 move more smoothly and smoothly in one direction. A second adjustment member 113 with a thread is provided in each through hole 112, that is, a screw or a bolt. The screw or bolt can not only fix the collimator assembly 1, for example, fix the collimator assembly 1 to the optical machine base 21, but also adjust the position of the collimator assembly 1 in one direction, for example, adjust the position of the collimator assembly 1 along the axial direction of the through hole 112. The collimator assembly 1 moves along the axial direction of the through hole 112 by the cooperation of the screw or bolt with the thread in the through hole 112.

[0046] In one embodiment of the present application, as shown in Figures 2 to 5, the rotation of the collimator assembly 1 within the plane of the slit width is adjusted by rotating the corresponding second adjustment mechanisms in the through-holes 112 of the first and second boss portions to different angles. For example, when the collimator is placed horizontally, by rotating the bolts in the first and second boss portions, respectively, when the two bolts are rotated to different angles, the collimator will rotate slightly within the horizontal plane, thereby achieving small-angle rotation of the collimator. Alternatively, when the collimator is placed vertically, fine-tuning of the deflection in the vertical direction can be achieved.

[0047] In one embodiment of the present application, as shown in Figures 2 to 5, the position adjustment portion 11 further includes a flat plate portion 114 having a plurality of flat plate holes 1141 and elongated slits 1142 corresponding to the collimator slits 125. The flat plate holes 1141 correspond to the adjustment holes 124, respectively. A boss portion 111 may be located at the end of the flat plate portion 114. Preferably, a boss portion 111 is provided at each end of the flat plate portion 114. The flat plate holes 1141 corresponding to the adjustment holes 124 are provided on the flat plate portion 114, so that a screw can pass through the adjustment holes 124 and the flat plate holes 1141 to adjust the flat plate portion 114 and the left and right collimator components 122 and 123 together. The flat plate portion 114 may include a left flat plate portion and a right flat plate portion, corresponding to the left and right collimator components 122 and 123, respectively. A narrow gap 1142 is left between the left and right plate portions to correspond to the collimator slit 125. Alternatively, in other embodiments, the plate portion 114 is formed of a single plate having a narrow gap 1142 greater than or equal to the collimator slit width.

[0048] In one embodiment of the present application, as shown in Figures 2 to 5, the collimator has a plurality of adjustment holes 124, wherein the inner surface of each hole and each hole in the flat plate hole 1141 is smooth, that is, the adjustment hole 124 and the flat plate hole 1141 are non-threaded holes, and the first adjustment member 121 passes through the flat plate hole 1141 and the adjustment hole 124 and is fixed to the shielding box 13 by a nut.

[0049] In one embodiment of the present application, as shown in Figures 2 to 5, the left collimator member 122 has a first protrusion 1221 near the collimator slit 125, and the right collimator member 123 has a second protrusion 1231 near the collimator slit 125. The first protrusion 1221 and the second protrusion 1231 surround the collimator slit 125. Accordingly, the flat plate portion 114 has an opening for the first protrusion 1221 and the second protrusion 1231 to pass through.
