Lens testing and calibration device

Abstract

The invention relates to a lens testing and calibration device, which includes a base, a test seat and a camera mounting seat. A connecting lens barrel is disposed on a camera. The lens testing and calibration device also includes a close-up lens placement rotary disc and more than two groups of test board device. The close-up lens placement rotary disc is connected onto the test seat and is provided with a plurality of close-up lens placement spaces. Each group of test board device includes a moving seat connected slidably with the base and a test board assembly mounted on the moving seat and capable of covering a field angle range of a lens under test or moving away from the field angle range of the lens under test. By use of different movable test boards and close-up lenses mounted on different positions of the close-up lens placement rotary disc, the device can quickly test and calibrate lenses of different focal distances only by slightly moving the test boards and rotating the close-up lens placement rotary disc in the case that a tester is not required to move back and forth with the test seat; and is not only simple and quick in operation and high in production efficiency, but also light in overall weight and easy to carry and transport.

Description

technical field [0001] The invention relates to a test and adjustment device, in particular to a detection and adjustment device suitable for matching with a monitoring camera in the on-line production of security fixed focal length, multi-focus and partial range zoom monitoring optical lenses. Background technique [0002] At present, in the production industry where optical lenses and cameras form a complete machine, it is necessary to detect and adjust each lens within a certain range of object distance on its matching camera. The usual method is: within 3 meters for different object distances When performing inspection or adjustment, the inspector needs to move back and forth with the bulky lens test stand, which results in high work intensity and low production efficiency. [0003] In order to overcome the above-mentioned defects, improve production efficiency, and complete inspection and adjustment purposes without the inspector having to move back and forth with the l...
