Hi everyone, I need to either buy or build a laser module capable of outputting a wide range of color via mixing the light from 3 or more diodes. I've already figured out the driver/color mixing part (I think). It will be an analog system controlled via a DAC, using a Teensy microcontroller.
My question is about the physical RGB array - I've seen the cheap ones on ebay that are made in China. My concern is that they will fail, plus, they don't tell you what diodes they are using, so I have no way of knowing how much current they can handle. Can anyone recommend a module that is decent (about 1 watt+ per color)?
Or would I be better off trying to build my own array with dichroic mirrors? It seems like it would be difficult to align the mirrors...
Any feedback would be appreciated.
