25mm Laser Beam Enhancement

Laser Beam Expander

Beam expanders/collimators can be used to either expand or reduce the laser beam diameter. The BEC-25 has a sealed design with easily removable optics. The adjustment ring allows for precise control of beam divergence, without rotating the optic or changing the overall length of the expander. Haas part number BEC-25-2.5-10.6 shown to the left.
