Metallic Cube Beamsplitters

Cube size ranges from 10-50 mm
Beamsplitter Coating for 400 - 700 nm

Holmarc's Metallic cube beamsplitters consists of two right angle prisms cemented together. The hypotenuse of the one prism has a combination of metallic-dielectric thin film coating. These are Lowpolarizing beamsplitters; the transmission and reflection for S - and P - polarization components are within ±10%. The cube faces of our beamsplitters have anti-reflection coatings for getting maximum transmittance. Beamsplitters with uncoated cube faces are also available. Custom sizes, coatings and split ratios are available as well.

Plate Beamsplitters

Plate beamsplitters find applications in splitting or re-combining a light beam. The front surface of our beamsplitter is coated with metallic...



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...
