Dimming of LED lamps including LED lasers is not like traditional dimming. The light source is switched on and of at a very fast rate. The difference between the on and off time gives a perceived change in brightness. So a source of a 500mw will still kick it’s full power but only in very short bursts. If you’re thinking of using a laser of the power your talking please do some research into laser MPE maximum permissible exposure . Even a very brief burst from a laser is enough to do damage so even when they are dimmed they can cause damage. Putting beam divergence lenses can diffuse the beam but you will still need to do the calculations. I’d also look into local authority licensing regarding lasers. I know that ANY crowdscanning no matter how controlled is banned in Manchester.

If a laser does this to a camera what’s it doing to your
eyes?
