25mm Laser Beam Enhancement Components

25mm Laser Beam Expander Collimator

Laser Beam Expander / Collimator : BEC-25

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 above. Download technical drawings for each stock part number on the right. Download free Adobe PDF reader and SolidWorks Viewer on the left.
