SF10 Brewster Prism
Description
Brewster Prisms are designed to have an apex angle such that a p-polarized ray incident at Brewster’s angle will pass through the prism parallel to the base at minimum deviation, and exit also at Brewster’s angle. In this case surface reflection losses are negligible. Brewster Prisms are often used in situations where surface reflection losses cannot be tolerated. Brewster Prisms are also frequently used to select a single wavelength from a multi-wavelength laser. Tuning is accomplished by tilting the prism. These prisms have very low surface reflection losses over the range 190-425 nm and are usable from 190-2500 nm.

Frequently Asked Questions
A Brewster Prism is a prism that is designed to allow a p-polarized ray to pass through at minimum deviation and exit at Brewster's angle, with negligible surface reflection losses.
Brewster Prisms have very low surface reflection losses over the range of 190-425 nm and are usable from 190-2500 nm.
Littrow Prisms are of the same design as Brewster Prisms but are cut in half vertically from the apex to the base. They are used to select a particular wavelength in a laser cavity or prism spectrometer.
Tuning with Brewster Prisms is accomplished by tilting the prism.
The specifications of Brewster Prisms include UV grade Fused Silica material, an apex angle of less than 10 arcmin, a clear aperture of more than 85% of central dim, and a surface finish of 10-5.
