Problems solved by technology
[0003] However, the first two mirror groups assembled are carried out by mechanical identification, and it is impossible to ensure whether there is tilt and decentration between the two mirror groups. Even if the final assembly is fine, if one of the two mirror groups assembled first has Tilt and eccentricity, then the entire optical system will have tilt and eccentricity, which will affect the normal use of the lens

Embodiment Construction
[0025] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.
[0026] Refer below Figure 1-Figure 3 The calibration method of the lens 10 according to the embodiment of the present invention will be described.
[0027] Such as figure 1 As shown, according to the calibration method of the lens 10 of the embodiment of the present invention, the lens 10 includes the first mirror group 11 and the second mirror group 12, and the calibration method of the lens 10 of the present embodiment is the first mirror group 11 and the second mirror group Mirror group 12 is adjusted and aligned, thereby can solve the problem of inclination and eccentricity of first mirror group 11 and second mirror group 12, like this, can improve the whole optical performance of lens 10, make the use effect of lens 10 better, lens 10 can be a zoom...

The invention discloses a lens calibration method and a lens. The lens comprises a first lens group and a second lens group, wherein the calibration method comprises the following steps that: S10, structured light is emitted from a first side of the first lens group to obtain a first pattern formed after the structured light passes through the first lens group; S20, the second lens group is placed on the second side of the first lens group, the structured light is incident from the first side of the first lens group, and a second pattern formed after the structured light passes through the first lens group and the second lens group is obtained; and S30, the first pattern iscompared with the second pattern, if the similarity reaches a first preset value, the relative position of the first lens group and the second lens group is fixed, and if the similarity is lower than the first preset value, the position of the second lens group is adjusted, and the step S20 is repeated. The first lens group and the second lens group can be aligned and adjusted, the problems of inclination and eccentricity of the first lens group and the second lens group are solved, after the first lens group and the second lens group are aligned, the whole optical performance of the lens can be improved, and the use effect of the lens is better.
Description
technical field [0001] The invention relates to the technical field of lenses, in particular to a lens calibration method and the lens. Background technique [0002] At present, the lens is generally equipped with at least two mirror groups. When the lens is equipped with three mirror groups, the assembly sequence of the three mirror groups is: firstly assemble the two mirror groups with mechanical alignment, and then use the assembly equipment to assemble the remaining mirror groups. When one mirror group is assembled, the assembly equipment can align the three mirror groups together, and glue is finally dispensed and fixed after the alignment is completed. [0003] However, the two mirror groups assembled first are carried out by mechanical identification, and it is impossible to ensure whether there is tilt and decentration between the two mirror groups. Even if the final assembly is fine, if one of the two mirror groups assembled first has Tilt and eccentricity, then th...
