Spatial Filters
Spatial Filters
Spatial filters are designed for use either intracavity as mode selectors, or extracavity to clean up the outer fringes of a propagating laser beam. All assemblies come mounted on a standard U.S. Laser carriage mount, and feature lockable 40 pitch micrometer thread X-Y axis adjustments. Individual aperatures are precision machined and threaded for easy removal and replacement.
