I still have some work to do sorting all the images that I shot during the development, so please bear with me.

Equipment

  • Pangolin Flashback3 DAC
  • ScanPro20
  • Aixiz 200mW/650nm module
  • Aixiz 75mW/532nm module
  • Blue laser extracted from C* projector with a Die4Drive laser driver (running at approx. 70mW)
  • 1x lasorb for blue diode
  • 3x optical mounts for dichroic mirrors
  • 2x dichroic mirrors (pass red/reflect green & pass red/pass green/reflect blue)
  • 1x front surface mirror for red beam alignment

chroma

Luminous flux contributions by wavelength:
445 nm: 2.0267 lm
532 nm: 42.304 lm
650 nm: 14.6162 lm

The blue diode is capable of outputting over 1W with coherent light, although not needed for this application as I only have 70mW/200mW of green/red. Need to keep it below 100mW in order to maintain white balance.

RGB

More to come..
