Quartz is a synthetic fused silica for the optics developed as the fused silica material for precise various optical components for the optics application and the high-power laser.

Corning 7980, ArF Grade, is a high purity synthetic amorphous silicon dioxide manufactured by flame hydrolysis. The noncrystalline, colorless, silica glass combines a very low thermal expansion coefficient with excellent optical qualities and exceptional transmittance in the deep ultraviolet. ArF Grade was developed for 193 nm lithography systems.

The optical glass are high purity, noncrystalline silica glasses that combine a very low thermal expansion coefficient with excellent optical qualities and exceptional transmittance. Characteristics include homogeneity, low birefringence and outstanding transmittance in the DUV, UV, visible, and infrared ranges.
Corning HPFS Fused Silica glasses are known throughout the industry for their consistent, repeatable performance. We offer many different grades of fused silica to support various product applications. Glass codes 8655 is high purity non-crystalline silica glasses with excellent optical qualities. Product characteristics include extraordinarily low refractive index variations leading to state-of-the-art homogeneity values, low birefringence values, large size capabilities, exceptional transmittance from the deep ultraviolet through the infrared region, and an ultra-low thermal expansion coefficient; all of which are critical to our customers demanding needs
 

Hellma Materials Barium Fluoride is the material of choice for wide bandwidth applications covering the VIS, near-IR and mid-IR range. It is an optical crystal grown from highly purified synthetic raw material and features a superior internal transmittance (T > 99% @7μm) enabling advanced applications in thermal imaging, night vision and surveillance imaging using integrated VIS and IR detector channels. Low spectral dispersion makes BaF2 the preferred optical material for aberration and color correction.

N-BK7 is designed and manufactured by Schott in Germany for a wide range of visible and short-wave infrared applications.

With more than 130 years of experience in the field of glass and optical technology, Schott's optical glass products play an important role in numerous industries worldwide
