Variable Laser Beam Expander

All optical elements of beam expanders are made of fused silica with high lidt coatings and provide stable and reliable performance even using them with high power lasers.

Variable laser beam expander. Variable beam expanders are ideal for systems where different magnifications and precise control of laser beam divergence are required. We also offer variable magnification beam expanders and reflective beam expanders. Variable beam expander manually adjustable or motorized for different wavelengths. These variable magnification zoom beam expanders are designed for required wavelength and each type of our beam expanders has a divergence adjustability.

This variability makes special optics beam expanders ideal for easier set ups on oem machines provides flexibility to equipment and are ideal for general laboratory research. Once the desired beam size and divergence is reached the position can be locked with two sets of screws. Beam expanders increase or decrease the diameter of a laser beam. Infinitely adjustable beam expanders deliver the high level of precision required in laser material processing.

Our variable beam expanders allow separate magnification and divergence adjustment. Techspec research grade variable beam expanders feature λ 4 transmitted wavefront galilean designs and high laser damage threshold ar coatings to ensure maximum transmittance while minimizing ghost reflections. Altechna offers variable beam expanders with high pointing stability and high lidt ar coatings that minimize ghost reflections. These laser beam expanders can be used with cw and pulsed laser sources and incorporate large input and output apertures so as to produce diffraction limited expanded or reduced beams for a wide range of input beams.
