Red Laser Beam Expander

Red Laser Beam Expander

Eternal Optics manufactures precision Red Laser Beam Expanders designed for 635nm, 650nm and 660nm visible laser systems, providing accurate beam expansion, reduced divergence, and improved beam quality for alignment, measurement, scanning, and precision optical applications.

A Red Laser Beam Expander is an optical component used to increase laser beam diameter while reducing beam divergence. By optimizing beam size before focusing or scanning optics, beam expanders improve optical system efficiency, enhance beam stability, and support higher precision in visible laser applications.
