01 / OVERVIEW

Beam splitter cubes for light separation and control

A beam splitter cube is an optical component designed to divide an incident light beam into two separate paths through controlled reflection and transmission. Constructed from two precisely assembled prisms with a specialized coating layer at the interface, beam splitter cubes provide stable beam separation with accurate optical performance.

Strahl Optics supports cube beamsplitters in polarizing and non-polarizing configurations for different beam separation requirements. Matching the prism pair and controlling the interface geometry keeps the cube structure consistent and supports reliable integration into optical assemblies.
