Variable Laser Beam Expander

These variable magnification zoom beam expanders are designed for required wavelength and each type of our beam expanders has a divergence adjustability.

Variable laser beam expander.

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. In doing so they enable different components of an optical system to adapt to one another. 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 beam expanders are ideal for systems where different magnifications and precise control of laser beam divergence are required.

Variable beam expander manually adjustable or motorized for different wavelengths. Infinitely adjustable beam expanders deliver the high level of precision required in laser material processing. 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. Altechna offers variable beam expanders with high pointing stability and high lidt ar coatings that minimize ghost reflections.

Beam expanders increase or decrease the diameter of a laser beam. With special optics zoom laser beam expanders variable magnification levels can easily be set ranging from 2x 8x 2x 10x 1x 4x and 1x 5x. Once the desired beam size and divergence is reached the position can be locked with two sets of screws. 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.
