Beam collimator
A leading European avionics/defense supplier bought from OSL a 235 mm clear aperture beam collimator enabling the company to precisely measure the quality of their imaging systems from the visible to the IR using Modulation Transfer Function (MTF) criteria. Beam collimators are optical assemblies that take divergent or convergent incoming light rays and produce parallel light output. They can be used to replicate a target at infinity without parallax.
