Low-light Night Vision Device Optical Axis Test Equipment
Uses and Main Features
The low-light night vision device optical axis test equipment consists of a large field of view collimator and a camera processing system, used to test the parameters such as the parallelism error and field of view of the binocular tube of the low-light night vision device. The large field of view collimator has the advantages of good image quality and large exit pupil diameter. Its light source illuminance range is wide, suitable for 1 ×10 -5 lx ～1×10 4 lx illuminance test products. The camera processing system can send instructions through the test computer, and use the software to drive the image acquisition card to acquire, store, record, display, and manage the image database.
