Features

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 1000:1 for beamsplitter made with N-BK7 glass, and better than 100:1 for beamsplitter made with UV fused silica. These cubes are recommended for use in pulsed laser systems and for purifying polarization in multimode, high-power lasers.

Proper Orientation

Cube beamsplitters are formed by cementing two right angle prisms together. One of the two prisms has the partially reflective metal-dielectric coating applied to its hypotenuse. In Newport's cube beamsplitters the coated prism is marked with a visible dot. Incident light should enter the prism with the coated hypotenuse in order to minimize power passing through the optical cement. Alternatively, a beam entering via the uncoated prism results in more than triple the fluence in the cement (the transmitted component, plus a double pass by the reflected component). With higher power beams this can result in degradation of the cement.

Multilayer Laser Line Coatings

Multilayer laser line coatings are offered for 13 laser wavelengths. UV coatings are shown.
