I'm continuing my tests, but I thought I would provide my .blend file so that other people could take a crack at making a lens collimator as well. The following render shows the raw, uncollimated beam emerging from a 0.5mm aperture with a divergence of approx. 3.5 degrees. The peg at the target indi...

Well, I'm getting close. I'll have to tinker some more to get the collimation tighter, though. The width of the peg at the wide end of the beam is the target beam diameter at 1 meter. I'm using a set of two lenses to collimate, but it seems VERY sensitive to the shape and thickness of the lens. I've...

Yes, photons are the end product, but Indigo cannot simulate the cascading electron effect that produces those photons. If it cannot simulate the light amplification, then it cannot simulate a laser. Sorry if I'm not explaining this very well, I'm trying my best. Also, I believe that beam divergence...

I haven't read this entire thread, but I think that I should point out that if we are aiming for realism it does not mean a beam with perfectly parallel convergence. All lasers in real life spread out, although the angle can be made to be very small with proper collimation optics. In fact, a typical...
