PS3 Violet + Red achromatic collimator?

[Chicxulub]

Is there ANY form of optic out there that could collimate a PS3 diode's red and violet at the same time? I'm getting really close to building a pink laser for the wife, and if I could get my hands on some sort of achromatic collimator it would make the process alot easier. I'm expecting to have to use two separate modules and dichros because divergence is important, but if there's ANYTHING that can do this, I'd really like to know about it.

Thanks for any help. I suspect though that if an achromatic collimator exists, it won't be cheap though. :-/

I'm pretty sure it doesn't exist. :-/ You're talking about a lens that treats red and violet differently, but in such a way that at a certain distance from the diode, both the 405nm and the 650nm lines will be collimated with the same divergence(and same beam waist).

I don't know, maybe if the initial divergence of the violet diode is different than that of the red so that a lens from some material will have a difference in refractive indexes at those wavelengths to collimate them perfectly.I'm just saying it's possible, but probably not very likely.

Else it's just gonna be something that splits them, collimates them individually and then combines them, but it's not really what you want.

well the actual PS3 sled uses a lens connected to a small motor, allowing it to focus for the different wavelengths - so you could possibly use something like that

again you're still limited to one color at a time

I thought this sounded plausable, don't achromatic lenses focus red and blue onto the same point? http://en.wikipedia.org/wiki/Achromatic_lens

Wow, that's what I was thinking about but I didn't think it actually exists. Now to find one in collimating lens form
