Plane Windows
Optical windows are used to isolate different physical environments while allowing light to pass relatively unimpeded. The selection of a window should consider the properties of the different optical materials, transmission, wavelength range, and resistance to the environment.
These products take many forms, sizes and shapes, and can either come round, square, or rectangular. Important dimensions to consider include the diameter of a round window, side of a square window, and length and width of a rectangular window. The thickness is also important to consider. Besides, a window can come either wedged or parallel.
We offer a wide range of different dimensions and shapes, as well as a variety of coatings that can be deposited on the windows. Manufacturing windows from BK7 to UV grade fused silica, other materials are available on a custom basis.
In addition, we offer different quality standards as described below. Surface quality ratings include 10-5 S&, 20-10 S&, 40-20 S&, 60-40 S&, and 80-50 S&. Choices for surface flatness for windows include ?/2, ?/4, ?/5, ?/8, ?/10, and ?/20.
We specialize in the production of medium to large-size custom windows with exacting tolerances, high grade surface finishes and difficult coatings.
