Fixed Magnification Laser Beam Expanders

Standa Galilean type fixed magnification Beam Expanders are ideal solution to expand or reduce your laser beam diameter. Our beam expanders are a good choice for both scientific and industrial applications. Simple non-adjustable beam expanders containing two or three lenses are often used because of their reasonable prices, simplicity and small size. Our beam expanders are compatible with our standard 5TLM-1TH, 5(M)BM, 5KOM or 5TOM series mounts. Convenient to use and robust design Computer optimized single wavelength design Anti-reflection coated optics Various magnfications from 2x up to 17x Low wave-front distortion (diffraction limited design) Typical applications include: Micro drilling LIDAR systems Beam condensing Colimation of laser harmonics Cutting of solar cells Laser structuring of foils Interferometers Colimation of high power laser beams General specifications Optics Material: FS or UVFS.
