WebA 3-element telescope relays the aperture plane to the amplifier with a collimated 0.5-mm diameter. The telescope contains a spatial filter pinhole. The nominal power levels are 3 mW into the preamp, 500 mW out of the preamp and 200 mW out of the aperture. A 6° angle of incidence bounce beam geometry is utilized in the amplifier cell. WebThe spatial filter assembly is made up of the microscope objective, a pinhole aperture and a positioning mechanism. Works With Most Objective Lenses The objective lens Z-axis motion is provided by a precision linear bearing, so that …
