The LC-075 10x Laser Collimator is optimized specifically for low wavefront distortion and diffraction limited performance at infinity focus in the visible wavelength region. The Galilean optical system is antireflection coated with visible MgF2 for maximum transmission. The focus is pre-adjusted for infinity prior to shipment, but can easily be altered and then recollimated. An oversized entrance aperture allows for easy alignment. These collimators mount conveniently in our cylindrical laser mounts.
