Laser Beam Expander for Laser Machine

Beam expanders are optical devices that take a collimated beam of light and expand its size (or, used in reverse, reduce its size).

In laser physics they are used either as intracavity or extracavity elements. They consist two or more elements which change the size and angular divergence characteristics of a beam passing through it. Beam expander are widely used in industrial laser marking/engraving and cutting system where the requirement to the laser beam quality is very critical. 

Star Optic carries the highest quality, compact, fixed and variable ratio beam expanders, organized by wavelength & ratio. Our aim is to offer an efficient and economical resource for quality, reliable beam expanders at attractive prices.
