Wanted: Cubed beam splitter

Tallaxo said:

Hi Rog, I think Andy wants a polarised splitter / combiner to effectively combine 2 beams of the same wavelength with minimal losses.  A dichroic filter will combine 2 different wavelengths effeciently  by reflecting one colour while allowing transmission of another if the lasers are directed at it at a 90 degree angle , with the dichro positioned at a 45degree angle to both.

Here is a schematic to explain what I mean
