Windows are used as substrates for a variety of applications, such as laser windows, output couplers, beamsplitters, beam combiners, mirrors, dichroic filters and plate polarizers. Considerations in selecting window substrates include transmission range, absorption coefficient, incident laser power density and environmental factors such as pressure, temperature, moisture, abrasion and corrosion.

Brewster Windows

Brewster windows are windows designed for use at Brewster's angle (usually uncoated). This is the angle where only incident p-polarized light has 0% transmission loss. They are an economical option for coupling linearly polarized light into sealed optical systems and to select the polarization of light traveling in optical cavities..

Wedge Windows

Large Wedge Windows greatly reduce or eliminate interference effects caused by multiple reflections between front and rear surfaces of plane windows. They are well suited for use as substrates for laser output couplers in which the reflection from the second surface must be completely eliminated from the gain medium of very sensitive lasers. Large Wedge Windows are also known as Interferometer Flats A pair of identical wedges are used to create an adjustable beam steering device.

Phoenix Infrared can design and produce a wide range of wedge windows to meet your specific application needs. Please contact us for additional information.
