25mm, VIS Beam Collimation Checkers, 400 - 700nm

SPV-25

Skip to the beginning of the images gallery

Beam collimation checkers (SPV-25/SPUV-25) are shear interferometers of the simplest design, used to examine the parallelism of laser beam expanders (collimators).

Details

Evaluation of the beam status on the μrad order is made possible by inserting a collimation checker in the optical axis, eliminating much of the time and labor required to adjust the optical axis and providing a superior quality beam. Beam collimation checkers are also compatible with beams of ultraviolet wavelengths. Contact our Sales Engineer for more information.
