We manufacture a variety of laser beam expanders for HeNe laser to suit most laser types. Wavefront distortion of less than λ/4 guarantees a minimum focused spot size even at long ranges. The lenses are anti-reflection coated with magnesium fluoride optimized for 632.8 nm, yielding transmission of over 95%.
These beam expanders can be conveniently attached to most HeNe lasers with the 1-32 accessory thread and are equipped with precision beam centering adjustments to compensate for slight decentration of the entering laser beam.
