UV optical windows ultraviolet transmitting focusing
in the (UV) ultraviolet spectrum of light transmission from
150nm to 400nm.
UV windows are fabricated in a range of optical and
crystal materials. Selection of ultraviolet windows depends
on a variety of factors as each material reacts differently
and each material is more suited to particular regions of
the ultraviolet spectrum.
UV Fused Silica Optical Windows
Fused Silica polished
windows have high transmission from deep UV @180nm
to 2000nm. UV Fused Silica has excellent thermal
properties with some grade fluorescence free and
deep UV applications using Krf (248mn) and Arf (193mn)
excimer lasers. Chemically inert with excellent
resistance to most chemicals.
UV Optical Glass Windows
There are grades of UV optical glasses
that transmit at the higher end of the UV close
to 400nm. Schott 8337b optical glass has 80% transmission
@220nm and has good transmission from 205nm into
the visible region widely used in sealing for
lamp manufacturers and UV systems.
Other UV optical and crystal windows for
ultraviolet transmission include UV grade calcium
fluoride (CaF2) and magnesium fluoride
(MagF2).
