Brewster Windows
Brewster Windows are uncoated substrates which are used at Brewster's Angle (the angle at which p-polarized light suffers no reflection loss). Brewster's Angle is calculated from:
B = tan-1(n)
where B is Brewster's Angle and n is the index of refraction of the material. At this angle p-polarization reflectance drops to zero. When used in a laser cavity, a Brewster Window causes the laser output to be polarized.

Standard Broadband AR Coatings
To order the wedged flat with a standard
broadband AR Coating, add the coating code to the Item#, and add the coating cost to the flat's price.
Wedge Flats are used primarily in laser beam steering applications. A beam normal to the perpendicular surface of the prism is deflected through the "Angular Deviation" shown in the price box. By combining two prisms that can be rotated independently, it is possible to direct the beam anywhere within the cone angle
Example: PS810 Coated with 350-650nm Broadband AR Coating is PS810-A and the cost would be $29.00 + $9.00 = $38.00.
