Inspection Requirements
This test product is made of glass and needs to be tested for dirty glass appearance.
The Solution
1. Infinitely long optical system that virtually eliminates chromatic aberrations and distortions for excellent picture quality.
2. Available in various magnifications, 40~220mm ultra-long working distance range for customization.
3. Excellent optical design, telecentricity less than 0.2°, aberration less than 0.3%.
4. Telecentric lens imaging is generally darker and needs to be used with a light source.

The imaging is clear and the dirt is easy to be identified.
The Lighting Source

Backlight is a flat panel light source, optimally designed LED arrays distributed at the bottom of the light source. The backlight passes through the special diffusion plate, which is 50% brighter than the side light guide.
