--Industrial light source

Bi-telecentric lenses have been well applied in the pursuit of higher precision and higher stability in visual inspection.

In bi-telecentric detection, the use of parallel light sources can effectively improve detection accuracy. In order to adapt to the market, Dehong Technology has specially developed parallel telecentric light sources, which is believed to bring more convenience to customers.

In a bi-telecentric lens system, a parallel light source has the following functions:

1.Improve image contrast and depth of field

2.Improve the sharpness of the image, especially the edge, and make full use of the camera resolution to improve the detection accuracy.

3. Eliminate the boundary effect and make the location of the edge

4, little interference to ambient light

5.Small size and easy installation

6.Long life of light source
