Multilayer V-Coatings

The hypotenuse of one of the prisms is coated with a multilayer dielectric polarizing beamsplitter coating optimized for wavelength at 405, 532, 1064, or 1550 nm.

Optical Contact for High Damage Threshold

These high power cube beamsplitters are formed by optically contacting two right angle prisms together. One of the two prisms has the partially reflective dielectric coating applied to its hypotenuse. Then a special process allows for the two surfaces to be contacted. Optical contacting is a difficult procedure and will work only if the two mating surfaces are very flat and very clean.  Because of the extra labor involved in optical contacting, this process is reserved only for higher power, more demanding applications.

High Polarization Extinction Ratio

An unpolarized beam is split into two orthogonal, linearly polarized components. P-polarized light is transmitted, while s-polarized light is reflected, both with negligible absorption. The extinction ratio is better than 200:1. This unique component provides all the benefits of a thin film plate polarizer in a standard cube configuration.
