Principle:
For example, when the light source shines in a tiny round hole, because the hole is relatively small, the light source passes through when a large part of the light has been dissipated, so that we can not see a clear image. Need to use Fennel lens to make the imaging light can penetrate the deep hole. Make the image clearly visible.
Based on the market demand, in line with the real problem-solving service for customers, Chuangshi Automation has developed and designed the telecentric lens module for this kind of inspection problem. Telecentric mirror module is cheaper, the price is the absolute advantage. At the same time the effect is not bad, more convenient, easier to combine. Field of view adjustment is more simple and convenient.
Features:
Class telecentric parallel light path, reducing aberrations, can be used with FA lenses to detect some large-size porous products.
Imaging light can penetrate deep holes.
Large field of view cost-effective (relative to telecentric lenses), in some of the requirements are not so high through-hole detection more advantageous.
Applications:
Filter cartridge through-hole inspection
Detection of clogged through-holes in deep holes
Low-demand positional measurement with drop-off
★Application examples
Regular lens + backlight effect Regular Lens + Telecentric Lens + Backlight Effect
