Profile: Lambda Research Optics, Inc. is a manufacturer of high-precision catalog and custom lenses, mirrors, beamsplitters, windows, prisms, filters and polarizers for laser applications. Our product line includes beam expander, radio polarizer, VeLo15 and UV optics. Our beam expander is a telescope in which a laser beam is expanded to a larger diameter. This can be useful to illuminate a larger area or to reduce the divergence of the beam. The radial polarized energy is better absorbed by mild steel than circular polarized energy. This effect will improve the cutting speed using the same amount of power since more power is now entering into the melt. We cater our services in custom coatings, fabrication and custom assembly.
