We can offers a wide selection of optical coatings covering a wide spectral range starting from the deep ultraviolet (170 nm) and extending to far infrared (20 mm).  Please refer to coating chapter for more information. Following is the brief introduction of several kinds of coating. 　

□Anti-reflection coatings
□High-reflection (HR) dielectric mirror coatings
□Partial reflecting (PR) dielectric coatings
□Wavelength Separating/Combining Coatings
□Hot/Cold mirrors
□Metallic coatings
□Hard carbon coating (DLC: "Diamond-Like Coating")
