Beam positionning before the dichro?

[allthatwhichis]

Damn that's perty! I use CD cases at the moment... I just got a aluminum plate off astroguy... It's 19 or so by 23 or so... I forget and can't see a tape measure. It's 3/4 inch think and heavy... I'm afraid to take what I got down. It'll take a wekk or two to get it back up...

A wekk or two is a Yorkshire saying (only the brits will understand)

We figured the easiest way to avoid using extra height compensating dichros, whilst at the same time keeping it all neat was to get different thickness aluminum "riser" plates machined up for us.

And if the lasers are not all lasing at the same vertical angle, regarding of the base plate (--> not straight)? The riser plates adjust the beam height at the laser's aperture, but maybe at the dichro it can be a little difference in height...

It's not the first time that I see this organization of the blue beam before entering the dichro filter, and I'm wondering why spend a extra mount and a mirror, instead of directly reflect the blue with the dichro?
Is it to have a better angle for the input of the green beam?

(I ask coz I'll soon receive my blue laser )

Hi,sbk,is this your RGB projector??

how much power of the blue laser?

[sbk]

Hi,
No it's not mine... But mine will be like this one in some days, when I'll receive my 100mW blue
(to add with 400mW red and 200mW green...)

I've been reading on the laserfreak forum a little and all these guys get 22.5 degree dichro's form a German supplier („HB-Laserkomponenten“).

Yes of course, that why we actually measure the beam height at the dichro, not rely on the Chinese specifications

For those of us... monitarily challenged, what are good riser/shims to use for laser height positioning? You know ghetto style for us bums... I just got a nice piece of aluminum off astroguy for a base plate, but my blue is a little taller than my green which is in turn a tit bit taller than my red... I have taken apert a couple of processor water cooling blocks but they are still, as my cousin would put it, "a cunt hair" off... I know most of y'all have a machinest in your back pocket but I don't even know of one.

So, if I go to home depot or walmart, what should I look for?
