Principle:
Plano-concave lenses diverge parallel light outwards. The focus of plano-concave lenses is negative, spherical aberration, coma, and distortion.
Features:
The plano-convex lenses produced by our company are usually made of K9 glass, and their anti-reflection coating is aimed at the wavelength range of 400-700 nanometers. UV quartz is also used as the substrate for processing. When UV quartz is used as the substrate, it has a good transmittance and a low coefficient of expansion in the ultraviolet region. It can be coated with a UV AR film for use under special circumstances.
Application:
The application of plano-convex lens: optical imaging, astronomical observation, scientific research, military industry and other precision instruments.
