Product Family Description

Elliptical beamsplitters maximize beamsplitting efficiency while minimizing required mounting space. When oriented at 45°, the beamsplitters create a circular aperture equal to the diameter of the minor axis. With an improved surface accuracy of λ/2, these beamsplitters are ideal for diffuse axial and in-line illumination integration. They are available in 50/50 beamsplitter coating and feature an anti-reflection coating to reduce back reflections.

Commercial Grade Elliptical Beamsplitters offer commercial quality, at an affordable price. Commercial grade optics have standard designs and are available on an ongoing basis. They are recommended for volume buyers or OEMs.
