| 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. |
