About 5% of a beam incident at 45 degrees is reflected from one surface of these BK7 beam samplers. The faces are parallel to within 5arcsec with a highly effective Anti-Reflection coating on the second surface. This coating eliminates virtually all ghost image problems. The 5% reflected beam is useful for diagnostic sampling or monitoring of the optical beam.
