Abstract

The invention relates to a five-degree-of-freedom positioning device for the point source transmittance test of the lens group, which relates to a positioning device, in particular to a five-degree-of-freedom positioning device for the point source transmittance test of the lens group, in order to solve the problem that the existing positioning device cannot To meet the positioning of lens groups with different lengths and different diameters, and the problem of not being able to adjust the angle of the lens group, it includes two first support arms, two second support arms, a base, a turntable, two first support rods, Two second support rods, two first vertical sliders, two second vertical sliders, two third connecting pieces and two fourth connecting pieces, each first supporting arm is made of an integral Composed of the first horizontal arm and the first vertical arm, each first chute is equipped with a first vertical slider, two first support rods and two second support rods are used to support the lens group, and the base is installed on the turntable The upper end face of the two can be detachably connected. The invention is used for the stray light test of the lens group.

Description

technical field [0001] The invention relates to a positioning device, in particular to a five-degree-of-freedom positioning device for lens group point source transmittance testing. Background technique [0002] In the stray light test of the lens group (that is, the test of transmittance), the transmittance of the lens group needs to be tested for incident light at different angles. A general light source, especially a large-scale solar simulator, has a fixed position, so the angle of incident light can only be changed by rotating the lens group, which involves positioning adjustment and angle control of the lens group. [0003] The positioning adjustment device of the traditional optical system generally cannot meet the positioning adjustment of lens groups of different lengths and diameters, and cannot realize a wide range of adjustment of the angle of the lens group, which has great limitations in optical testing. Especially for a lens group with a light shield, its dia...
