Coated Optical Neutral Absorptive Filter Dia25.4xT6mm OD1
Product Description
CPG OPTICS offers very high coated and uncoated interference filters. We have developed a test method to guarantee the surface flatness and surface quality.
All filters from CPG optics are used as standard test plate or in astronomy, we are very proud to tell and provide the fabricating service for the customers.
Materials we already use: optical glass, materials, and even some plastics.
