I did a dichro test on the reflect blue dichro.
I tested the losses of a H & V polarized 655nm red beam.
I have chosen for the red laser only becouse this is a diode lasers and is very stable. a DPSS can heat up during the test and give altered readings.
Without the reflect blue dichro in the beam path my red measured 272mW
With the laserwave dichro in the beampath I measured 235mW
Laserwave give a loss of about 13,6%
With Phil's Dichro in the beam path I measured 260mW
Phil gives a loss of about 4,4%
I also measured a waste beam from the laserwave from 50mw!!! phils dichro got a waste beam of 6mW
I know you guys like pictures so here we go:
