Anamorphic prism shenanigans

[clickamouse]

Greetings, my fellow laseristas;

I have a question about prisms: is the following "legal"?



In other words, if I tilt the final prism a hair, can I get it to steer without wrecking the beam correction I'm going for?

Thanks…Mike

Yes, I used to do it all the time when I used more prisms for 445nm beam magnification. The prism does not create any type of angle related distortion. It is just a mater of angle related magnification that is even across the beam. The reflective loss from the prisms grows with the angle of incidence and so by dividing the magnification between the two prisms this is minimized and the beam can be sent through with no deviation, but this is not a requirement. As a side note, these prisms and telescopes don't really "correct" the beam. They trade near field beam diameter for far field divergence.

I love your little gems such as this one. Easy to remember.

Gotcha; much thanks.
Great explanation.

I might also be moving the Stanwax board to the other side of the plate; still working on it.

Actually, in kinetic lighting one often does little tricks like thing to add additional movement. Ideally I want as many bits of control as possible. - now that I'm beginning to use lasers I am seeing that a lot of the same stuff can be applied but in some cases one ones have to consider whether image detail is as important as effect
