Fused Silica UV Windows
UV
fused silica windows are commonly used to isolate two atmospheric regions of an
optical system while permitting light to pass.
The quality of the window can be critical. It should be of high purity and polish in order not to affect
the optical system. When large
pressure differences are anticipated across the window extra thickness will be
required to hold the flatness and parallelism specifications.
UV
windows are supplied in a wide range of shapes and to various levels of flatness
and parallelism:
Shape:
Circular, Square, Elliptical
Flatness:
λ/10, λ/4, λ/2,
2λ per 25mm.
Parallelism:
10 arcsec, 3 arcmin
Wedge:
0, 30 arcmin,
1°, 2°,
3°
We
can supply circular UV windows in diameters of 10.0, 12.7, 19.1, 20.0,
25.4, 30.0, 38.1, 40.0, 50.8 mm or any custom size.
We
can supply square optical windows in sides of 10.0, 12.7, 19.1, 20.0,
25.4, 30.0, 38.1, 40.0, 50.8 mm or any custom size.
We
can supply elliptical optical windows with a minor axis of 12.7, 15.0,
19.1, 25.4 mm or any custom size.
