A ZnSe focus lens is an optical element used in infrared optical systems to focus, collimate or reflect infrared light. ZnSe is widely used in the mid-infrared and far-infrared wavelengths (2-20 microns) due to its excellent light transmission and mechanical properties.
What are the precautions to be taken when installing a ZnSe focus lens?
1. Focus lens is installed with the convex side facing up.
2. After replacing the lens, you need to fine-tune the lens barrel up and down.
3. Fixed in the best cutting effect position.
CVD ZnSe is the first choice of optical components for high power CO2 lasers to its wide transmission band and low absorption in the red portion of the visible spectrum.
