On Thursday Feb. 9, Ralon Labs had a visit from Linköping University,

ITN Campus Norrköping. Stefan Gustavson, Jonas Unger and Jonas Lindqvist, involved in a research project on high dynamic range

image acquisition at video frame rates, needed a beamsplitter for

RGB color separation with a large aperture and high light throughput.

The beamsplitter and lens were salvaged from an old 3-LCD digital

projector. A rough setup for testing was made at Ralon labs, and

the solution proved adequate for the purpose, although search goes

on for an alternative solution that does not require polarization.
