Hi I need one of these Dichroic Beamsplitters for the DOTs output for the laser sky effect. It will go in front of laser and produce many dots. I have one now but need another one. any help out there? thanks John :wave: :confused:

I think you mean diffraction gratings, though maybe not if you want liquid sky.
It seems what you request are two different things
Liquid Sky:

Diffraction grating(you refer to):

Liquid Sky is done by scanning a laser beam left to right and
back again at a high rate of speed.

I haven't seen any diffraction gratings that can do that.

you can use a line generating lens to get the liquid sky effect, however the brightness would be greatly diffused.
just get a polygon mirror and a simple electric motor
