Plate Beamsplitters

Circular and square aperture available
AR coating on back side minimize the unwanted secondary reflection

Plate beamsplitters find applications in splitting or re-combining a light beam. The front surface of our beamsplitter is coated with metallic or dielectric thin film and the back surface is AR coated. The antireflection coating on the back surface minimizes unwanted secondary reflection. Holmarc offers beamsplitters in three R/ T ratios; 30/70, 50/50 and 70/30. Custom R/T ratios and sizes are also available. Though our standard plate beamsplitters are designed for visible region between 400 nm and 700 nm, we can also provide these optics for ultraviolet and Infra-red spectral regions.

Variable Beamsplitters

Our Circular Variable Beamsplitters (Mounted ) find applications in splitting an incident beam into a transmitted and a reflected beam.



Beam Samplers

Beam Samplers are used to pick off the sample of a light beam by using the Fresnel reflection from uncoated surfaces. Beam samplers are used for monitoring...
