Cut-off Colored Glass Filters The glass is named based on spectral characteristic of which is represented by the wavelength transmission limit. Short Pass Color Glass Filters Long Pass Color Glass filters

Selective Absorption Colored Glass Filters This part of the glasses can be divided into 14 kinds and 78 types based on the color and application in this catalogue.

Fused Silica material Advantages With Good UV and IR transmission, Low thermal expansion, providing stability and resistance to thermal shock, Wider thermal operating range and High laser damage threshold make Fused Silica windows could used for Laser, Medical, imaging etc. application.

Optical Silver Coated Mirrors Average Reflectance >90% from 400 nm to 20 µm Shape could be customized: Round, Square, Elliptical, Right angle prisms Material could be customized: Fused silica, Pyrex, N-BK7

Precision Aspheric Lenses Collimate or Focus Light with a Single Element Reduce spherical aberration Reduce overall system weight

Schmidt Prisms Schmidt prisms are used to invert and revert an image to angle of 45°. The 45° deviation makes Schmidt prisms useful in eyepiece assemblies and imaging systems requiring a path bend. 1. Ray Deviation of 45° 2. Right Handed Image 3. Combine with Half-Penta Prism to Create Pechan Prism
