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. |
