Abstract

The invention relates to a detection instrument for an industrial lens, in particular to a projection detection device for the industrial lens. The device comprises a base plate. The upper end face ofthe base plate is a plane, a support is arranged on the base plate, a top plate is arranged on the upper end of the support, and a lens installation clamping position used for installing an industrial lens to be detected is arranged on the top plate. A backlight and a mobile loading frame placed above the backlight and movably connected with the support are arranged between the top plate and thebase plate, a test chart is arranged on the loading frame, the lens installation clamping position is opposite to the test chart and the backlight, and the distance between the test chart and the lensinstallation clamping position can be adjusted by the movable mobile loading frame. Furthermore, the distance between the test chart and the industrial lens to be detected can be adjusted by the movable mobile loading frame, and therefore a back focus adjusting function is achieved.

Description

【Technical field】 [0001] The present application relates to a testing instrument for an industrial lens, in particular to a projection testing device for an industrial lens. 【Background technique】 [0002] The detection of industrial lenses generally adopts the method of projection detection. The chart is irradiated by the light source and then forms an image on the projection surface after passing through the industrial lens to be tested. The detection of the industrial lens is completed through the detection of the imaging quality, but the chart of the general detection instrument is fixed. Yes, the distance between the industrial lens to be tested and the chart cannot be adjusted, so it cannot be applied to industrial lens tests with different back focus. 【Content of invention】 [0003] In order to solve the problem of low applicability of industrial lens projection detection instruments in the prior art, the application provides a projection detection device for indust...
