Variable Beamsplitters

(Mounted)

BK7 and Fused silica material of thickness 3 mm
Splits incident beam into a transmitted and a reflected beam

Our Circular Variable Beamsplitters (Mounted) find applications in splitting an incident beam into a transmitted and a reflected beam. The intensity ratio of transmitted and reflected beams can be controlled over a wide range. The front surface of the variable beamsplitter has protected aluminium coating and the back surface has anti-reflection coating to reduce secondary images.
