One interesting experiment would be doing this in reverse. In theory the optical system should work exactly the same, so you combine the beams with the dicro and get 3 shooting out of the cube on 3 sides.
I almost pulled another set of dichros off my projector to keep the combining and splitting party going further down the chain - but what you mentioned would be easy and fun, too! If I can get some time tonight I might update the thread!
Thx for the feedback! :beer:

Sorry, didn't mean to leave you hangin' there! Thx for the kind words, too...
So - that "405nm" looking beam is in fact a 445nm- but depending on the angle of the camera compared to the beam, and also the power output of the beam, the blues can get tricky in pictures!
As for cheap sources - the dichros I bought from a CN seller "lilly-marie' - "she" has both an Amazon and fleabay presence. The stands for the dichros I got from Aixiz. Cheap prisms - depending on what you are after, can be found by the dozens on Amazon - but I like to find 'gems' (dual meaning) at flea markets, Goodwills, and spiritual shops. At least when I'm going for something unique / some variety. As Hakzaw mentioned, the X-Cubes I would go to fleabay. I think that is where I have gotten all my cube-shaped combiners. (
Heres an XCUBE)
If you are going to try combining RGB, you will want a lower power green, for sure. It does not take much green as the eye finds that part of the visible spectrum 'brightest'. There is a nice wavelength-power/brightness calculator out there, if you search for it with the bottom search in the forum.
I do use a fog machine when it comes to indoor "lower" power laser pics/vids. Makes a ton of difference.
Good questions - LMK if you have any other thoughts! Thanks again for checking it out
