AR coated Colour glass window
Color glass changed the spectral properties of optical radiation. They therefore allow scientific experiments and industrial applications where that change is necessary. You can combine color glass filters together to change the bandpass or to increase the attenuation.
Sapphire Crystal Windows
AR Coated Sapphire Windows
Sapphire window retains its high strength at high temperatures, has good thermal properties and excellent transparency. It is chemically resistant to common acids and alkali at temperatures up to 1000 °C as well as to HF below 300 °C. These properties encourage its wide use in hostile environments where optical transmission in the range from the vacuum ultraviolet to the near infrared is required.
