Fused silica is the glassy form of quartz and is thus isotropic. It is tough and hard and has a very low expansion. Normal varieties contain water which gives strong absortion in the IR. Water-free varieties are available.
There are different types Fused Silica used for different application. We mainly have three types, including JGS1, JGS2, JGS3. Click here for the application and their equivalent to other Fused Silica supplier and our prices our usually much lower.

is formed by chemical combination of silicon and oxygen. Fused Silica is perfect optical material due to its good UV and IR transmission, low coefficient of thermal expansion. It has high stability and resistance to thermal shock over large temperature excursions, wide temperature operating range and high laser damage threshold.

:is transparent in the ultraviolet and visible regions. It has no absorption hands in 170-250 nm wavelength intervals and has intensive OH absorption band in the interval of wavelength 2600-2800 nm. JGS1 is used for optics operating in the deep UV and the visible wavelength range (Laser Lenses, Windows, Prisms, Mirrors, etc.). It is practically free of bubbles and inclusions.
Fused Silica is similiar to the following Manufacturers
Heraeus - Suprasil 1 and 2
Saint-Gobain - Spectrosil A and B
Dynasil's 1100 and 4100
benefits include good UV and visible transmission similiar to JGS1. Can be made in small diameters/dimensions that can be very thin and is free of bubbles. Cons include possible bubbles in larger dimensions/diameters.
JGS2 Fused Silica is similiar to the following Manufacturers
Heraeus' Homosil 1,2 & 3
Dynasil 1000 & 4000 & 5000 & 6000
Applications for JGS2 include condenser optics, high temperature and pressure applications, optical flats, microscope slides and sight glasses.
is transparent in the ultraviolet, visible and infrared spectral regions. It's absorption bands are in the 185-250 nm spectral region, but has no absorption bands in the visible physical properies with outstanding optical characteristics in the deep UV and the IR wavelength range. It is those requiring very wide wavelength range from DUV to MIR. It is quite a bit more expensive than Silicon and slightly less expensive than Calcium Fluoride or ZnS Multi-spectral grade.
JGS3: is similiar to the following manufacturers
Heraeus Suprasil 300
