Okay, I guess I understand now. these powerful diodes diverge in the X axis a lot and have long "feathers" just after few meters (like my 300mW shitty red module in my projector). The prism pair doesn't affect the "Y axis", but shrinks the beams in the "X axis", thus making the dot appear more of a circle than a long horizontal line. Got it.
Do these modules use active cooling?
And btw, why so many lower power red diodes instead of few 700mW and a prism pair like they did for the green and blue? Wouldn't it be more cost effective and less time consuming for them?
the lightspace modules do have active cooling, and yes there's some feathering around the spot. most evident in the red. it would be worth trying to spatial filter them.
suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.
