Description

Technical Field

[0001] This invention relates to the field of lens polarization testing technology, specifically to an optical lens residual polarization testing device. Background Technology

[0002] Optical lenses are essential components in machine vision systems, directly affecting image quality and the implementation and effectiveness of algorithms. Optical lenses can be categorized by focal length (short focal length, medium focal length, long focal length), field of view (wide-angle, standard, telephoto), and structure (fixed aperture fixed focal length, manual aperture fixed focal length, automatic aperture fixed focal length, manual zoom, automatic zoom, automatic aperture motorized zoom, motorized triple-variable zoom, etc.). Industrial optical lenses are widely used for locating and detecting objects with extremely high reflectivity. Polarization refers to the phenomenon where the vibration vector of a transverse wave is deflected in certain directions; polarization data directly affects the quality of optical lenses.

[0003] Current optical lens residual polarization testing devices can only achieve measurements within a limited angular range. For example, the common method of rotating the lens at fixed angle intervals for testing is not only inflexible in angle adjustment, but also has a limited range of detectable angles. In some practical application scenarios, the incident light angles of optical lenses are diverse and complex, making it impossible for existing testing devices to fully grasp the residual polarization characteristics of the lens under different incident angles. Therefore, an optical lens residual polarization testing device is proposed. Summary of the Invention

Rotating the knob 471 causes the threaded rod 47 to rotate, and the threaded rod 47 causes the U-shaped clamps 48 to move, thereby clamping and fixing the optical lens.

[0040] In operation, the present invention works as follows: First, two optical lenses to be tested are placed between two U-shaped clamps 48. Rotating knob 471 causes threaded rod 47 to rotate, which in turn moves the U-shaped clamps 48 to clamp and fix the optical lenses. Then, according to the testing position, the position of the optical lenses is adjusted. The first motor 22 is started, causing lead screw 23 to rotate, adjusting the position of the second fixing plate 24 and thus the position of the optical lenses. Finally, the test lamp 171 is activated, illuminating the optical lenses with light. The light then passes through… The optical lens receives feedback on the photosensitive plate 182. When it is necessary to detect different angles of the optical lens, the second motor 35 drives the second gear 36 to rotate, the second gear 36 drives the first gear 34 to rotate, thereby adjusting the angle of the first connecting plate 33.
