We have a Planetarium installation where we want to augment two channels of larger Laser imagery plus our Fulldome video with another channel of imagery from two daisy chained 1 to 2 watt RGB mini lasers up in the cove lip. In the past we have done this with multi mode lasers, fiber optics, and big mirror 12k Cambridge scanners for mainly beams, projected through movable opening dome ports.
Chopping up the dome is a no go in this case, the available space in the cove lip depth is about 9 inches or so, I'd like to avoid the fiber optic dance, and too much laser power will sometimes drown out the stars and 360 video. In an era where lots of laser power has never been cheaper, we seem to be "playing in the cracks"
Could anyone suggest a reasonably reliable supplier? Most folks have stopped making stuff in small low watt output machines. Ebay has lots of $300 to $500 systems that appear to be small enough do the job with the right power, but who are the manufacturers where you have a fighting chance?
20k scanning is not the end of the world, we've got decades of shows with that imagery channel at 12k that we can convert to RGB, analog color mod would be preferred, ILDA in & out is required, I've heard 520 green is better, we can build a shelf to extend out a bit, but vertical size height above the spring line is critical
Sorry to ramble on, but any tips would be a great help.
Thanks in advance.
