We supply Ohara natural quartz made from high-purity crystals. Both hydrous and anhydrous (low OH content) quartz with low bubbles and high heat resistance are available.

This is based on AGC's years of accumulation of precision glass, precision chemistry, precision ceramics technology and research and development and manufacturing. Suitable for the semiconductor process, is widely used in a variety of optical components of high purity, high quality, high function glass.

NIFS series features a homogeneous refractive index, high transmittance and superior laser durability.
The NIFS series has been developed and manufactured based on nearly 100 years of experience in optics. Various grades are available for different sizes and applications, as well as for numerous optical properties such as wavelengths.
 

Chemically vapor-deposited CVD Zinc Selenide® is the material of choice for use as optical components in high-powered CO2 lasers due to its low bulk absorption at 10.6 µm. Its index of refraction homogeneity and uniformity offers excellent optical performance for use as protective windows or optical elements in high-resolution forward-looking (FLIR) thermal imaging equipment.

OHARA CLEARCERAM-Z is a kind of microcrystalline glass with ultra-low coefficient of thermal expansion
This material was developed by ohara based on high uniform melting and precise crystallization.

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
"N"-glass as an environmentally friendly alternative to conventional lead and arsenic-containing glass types.

Ohara optical glass serves as the cornerstone of advanced optical systems and is widely used in digital devices, such as digital cameras, cellular camera phones, and LCD projectors. Our leading edge materials are also used in optical devices such as microscopes and astronomical telescopes.

Germanium compounds and products are created during the various stages of the production flowsheet from raw materials to semiconductor substrate. Starting with Germanium concentrate chlorinated and purified into GeCl4 , GeCl4 hydrolized to GeO2 and GeO2 reduced to Ge bars. The Ge crystals are grown using Czochralski crystal pulling and further processed into either high purity crystals or Ge semiconductor wafers.

Hellma Materials BaF2 features an excellent transmittance in the VIS and IR spectral ranges up to 12µm.
This allows the usage of BaF2 as broadband optical material in the VIS and IR dual-channel systems for visible and thermal imaging.
BaF2 has a lower refractive index than many other optical materials. This reduces transmission losses caused by Fresnel-reflection.
