Beam
Samplers |
| |
| These beam-samplers are
useful for beam diagnostics and monitoring. They are manufactured
to work at 45 degrees incidence. When they transmit the main beam,
they sample 4% of the input or so. The sample beam is provided by
the natural reflectivity of the surface. The back surface with broadband
antireflection coating can eliminate errors from back surface reflections
with a high efficiency.
