Optical Windows
Optical windows are used to isolate different physical environments while allowing light to pass relatively unimpeded. Our optical windows can either come round, square, cuboid and other especial windows. Important dimensions to consider
include the diameter if a round window, side if a square window, and length and width if a cuboid window. The thickness is also important to consider.
A window can come either wedged or parallel. A problem with parallel substrates
is that the second surface reflection can lead to unwanted spectral channeling.
Reflections from the surface of the wedge are not parallel and also slightly separat
-ed. The parallelism or wedge angle is important to consider, this unit is specified
in arc minutes for both. Surface quality ratings for optical windows include 10-5 ,
20-10, 40-20, 60-40, and 80-50(scratch / dig).
Coatings for optical windows include none, antireflective, and conductive.
Common materials of construction for optical windows include BK7 glass, crown
glass, calcium fluoride, germanium, sapphire, UV grade fused silica, float glass, etc.
For corresponding specifications,
