With such a lower power in the blue , slow photopolymer
Probably is not the best way to go, I’ll do some blue transmission next using silver film ... I need to install
3 RGB toggle switches so I can run a longer exposure
Time on the blue , then flip the switch to shut off red and green ..

Impressive Dave. Do you also use a TEC controller or only current control?

We need a like button :)
I may have to buy a full colour unit of you as well.

When handling your light engine be very cautious of the green turning Mirror,(pictured below), as it’s very easy to knock that off while you’re holding the housing!

I was thinking the module is laying on a table but it isn't it is laying on your hands. The lasermodule is unbelievable small.
