It incorporates a lensed IR LED and phototransistor elements to collimate
the light beam for enhanced resolution at a detection range from 0.
However, unfortunately in the present time we must collimate
our incident beam very severely to minimize the leakage radiations in order to maintain very low background radiation level in our neutron guide hall to aviod possible influence to neighboring experiments.
The unit utilizes new patent-pending Collitron eyepiece holders that allow the user to precisely collimate
the unit without tools, and both sides focus with non-rotating helical motion.
As an added feature, nLight can include an AR-coated cylinder lens to collimate
the fast-axis to <2[degrees], FWHM, with >95 percent power transmission.
So what are we trying to do when we collimate
This is why you should collimate
your scope--you want to ensure you're viewing the very best part of the primary's focal plane.
