LASERWORLD RS-800 RGY Modificatioin to RGB Help!

[miking1834]

Ok, converting my laserworld to rgb. It originally had a cube optic with two red laser diodes. I now have a 400mw Blue and a 500mw red I wish to install of the place of the two reds. Will the existing cube work for this or do I need different optics? Also I am worried about blowing my new blue diode up due to improper grounding. Any advice would be much appreciated! Thanks

You need a dichroic filter to joint red and blue together (your case you need: pass red and reflect blue dichro).
A PBS cube (the cubic optic which you wrote) is used to joint two same wavelength lasers or wavelengths very close between them(example 642/638nm or
650/650 ...). If you use that PBS cube you do not obtain the right color (purple) because their wavelengths are too far between them (blue=445 or 473nm; red= 635/638/640 or 650nm) and you also could damage one or both laser module because direct reflection.

Just for record... take the other dichro mounting off from the baseboard. Let change it. That kind of mounting+dichro filter are a real huge crap. I now this for sure bacause I had the same projector of your. I become crazy to allign colors ....
