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.
