Conclusion: Laserwave dichroics reflectivity is >99%, and transmissivity is >97%. But obviously, some other suppliers’ dichroics have a high loss.（especially the Blue. Personally, we think when coating the mirror, they only consider to reflect Red & pass Green, not didn’t consider the Blue. But 637nm Red is the most expensive laser, if you put the Red laser nearest the scanner, when you use this kind of dichroics, the Blue will loss too much） So when you buy Laserwave dichroics, maybe you spend a little more money, but it keeps your laser a higher power , actually you get more.
