Vacuum spatial filter are designed for use with high power laser systems to control beam quality, prevent air breakdown, beam expand, image relay and retard nonlinear self-focusing. FEATURES • Standard sized chamber with custom arm diameter and lengths will accomodate beam diameters from millimeters to tens of centimeters. • External lenses with X-Y-Z micrometer positioning. • Pinhole positions can be quickly switched out of the beamline without breaking vacuum. When requesting a quote, please specify: • Wavelength • Energy • Pulse Length • Beam Diameter • F# or Focal Length • Pinhole Size • Magnification • Beam Height
