Optikos Corporation has developed a new series of Glare Spread Function projectors, the first instance of which is designated the Sol-55. This projector provides manufacturers of small aperture cameras with a means to evaluate the Glare Spread Function performance of these cameras by projecting a collimated and uniformly illuminated circular target into the entrance pupil of the Device Under Test (DUT).
The instrument consists of a configurable projector in which the user may manually alter the angular extent of the projected target and the diameter of the pupil to be illuminated. The brightness of the target illumination may be set over a remote electrical interface, and the distance to the entrance pupil may be factory configured.
