Laser Beam Expander

Beam expanders are used in laser physics either as intracavity or extracavity elements. They can be telescopic in nature or prismatic. Generally prismatic beam expanders use several prisms and are known as multiple-prism beam expanders.

Beam Expanders/Collimators are designed to expand or reduce the laser beam diameter. Adjustable divergence control ring allows precise calibration. Sealed design prevents contaminants from entering into the beam path. The unit has a 19 mm output aperture and both ends have a 1”-32 female thread.
