Variable Laser Beam Expander

Once the desired beam size and divergence is reached the position can be locked with two sets of screws.

Variable laser beam expander.

In doing so they enable different components of an optical system to adapt to one another. 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. 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.

Our variable beam expanders allow separate magnification and divergence adjustment. Techspec research grade variable beam expanders rvbx are ideal for high power laser applications where magnification changes may be required such as prototyping or r d. 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. We also offer variable magnification beam expanders and reflective beam expanders.

Infinitely adjustable beam expanders deliver the high level of precision required in laser material processing. 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. These variable magnification zoom beam expanders are designed for required wavelength and each type of our beam expanders has a divergence adjustability. Beam expanders increase or decrease the diameter of a laser beam.
