Fused Sillica Optical Windows

We are offering fused sillica optical windows. fused sillica optical windows*fused silica is formed by chemical combination of silicon and oxygen. Advantages of fused silica material include good uv and ir transmission, low thermal expansion, providing stability and resistance to thermal shock over large temperature excursions, wider thermal operating range and high laser damage threshold. Used for windows, lenses, prisms and mirror substrates. specifications: material:uv grade fused silica dimension tolerance:+0.0, -0.1mm thickness tolerance: 0.1mm surface quality:60/40(standard), 10/5(high precision) clear aperture:>85% flatness:(standard), /10(high precision) per 25mm@633nm parallelism:1' (standard), 10" (high precision) bevel:

Sapphire Optical Windows

We are offering sapphire optical windows. Sapphire optical windows*single crystal sapphire possesses a unique combination of excellent optical, physical and chemical properties. The hardest of the oxide crystals, sapphire 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. Sapphire is anisotropic hexagonal crystal. Its properties depend on crystallographic direction (relative to the optical c-axis). *specifications: material: sapphire dimension tolerance: +0.0, -0.1mmthickness tolerance: 0.1mmsurface quality: 80/50clear aperture: >85%flatness: per 25mmparallelism: 3' bevel:

Caf2 Optical Windows

We offer caf2 optical windows. *calcium fluoride (caf2) is an insoluble ionic compound of calcium and fluorine. calcium fluoride is commonly used as a window material for both infrared and ultraviolet wavelengths, since it is transparent in these regions (about 0.15 m to 9 m) and exhibits extremely weak birefringence. Furthermore the material is fairly inert chemically so that these windows are not attacked. Nevertheless, at wavelengths as low as 157 nm, which are interesting to semiconductor manufacturers, the birefringence of calcium fluoride exceeds tolerable limits. This problem with birefringence can be mitigated through optimised growth process. It is particularly important as an ultraviolet optical material for integrated circuit lithography. Fluorides are toxic to humans, however caf2 is considered relatively harmless due to its extreme insolubility. *we provide artificially-crystallized calcium fluoride components available in ir grade and uv grade. The cost of uv grade is much expensive than ir grade. *specifications: material: sapphire dimension tolerance: +0.0, -0.1mm thickness tolerance: 0.1mm surface quality: 80/50 clear aperture: >85% flatness: per 25mm parallelism: 3' bevel:

Optical Silicon Windows

We are offering optical silicon windows. *silicon (si) is grown by czochralski pulling techniques (cz) and contains some oxygen that causes an absorption band at 9 microns. To avoid this, material can be prepared by a float-zone (fz) process. Optical silicon is generally lightly doped (5 to 40 ohm cm) for best transmission above 10 microns, and doping is usually boron (p-type) and phosphorus (n-type). After doping silicon has a further pass band: 30 to 100 microns which is effective only in very high resistivity uncompensated material. cz silicon is commonly used as substrate material for infrared reflectors and windows in the 1.5-8 micron region. The strong absorption band at 9 microns makes it unsuitable for co2 laser transmission applications, but it is frequently used for laser mirrors because of its high thermal conductivity and low density. Application as window, lens in the 1.5 - 8 um region; mirror for co2 laser and spectrometer applications. *specifications: material: si dimension tolerance: +0.0, -0.1mm thickness tolerance: 0.1mm surface quality: 60/40 clear aperture: >85% flatness: per 25mm parallelism: 3' bevel:
