Below are just a small expample of the Fused Silica wafers that we have in stock. We can also custom make any spec!
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.
JGS1 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.
JGS1 Fused Silica is similiar to the following Manufacturers
Heraeus - Suprasil 1 and 2 Saint-Gobain - Spectrosil A and B Coming's 7940 Dynasil's 1100 and 4100
JGS2 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
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
JGS3 Fused Silica 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.
