Default Kvant RGB Modules

Just accidently stumbled into Kvant RGB modules on interweb.

800mw Module >>

1800mw Module >>

There's not much info and RGB modules divergence is given as Half angle, and I'm trying to figure out true divergence.

Any mathematicians or knowledge/help would be much appreciated!


Thanks!

If the half angle is given in mRad then multiply by two. However 0.4 mRad is very low for 637nm. Nice find ArcticDude, but Kvant is very expensive. €1056 for their 800mW module including tax.

Thanks Curtis for your input!

Yeah, that makes me wonder is there some corrective optics inside of RGB module?

1.8W module has almost identical divergence but other hand 24V voltage requirement makes this module little unpractical for portable use...

Does anyone have first hand information is there corrective optics or maybe seen Kvant RGB 800 / 1800 modules opened?

Default Re: Kvant RGB Modules

I can gather that they would use corrective optics inside most of their modules as they are known for their high quality. Without actually having one and opening it up, we don't know for sure.

Default Re: Kvant RGB Modules

These guys can also produce 607nm in portable builds between 50 and 200mW, depending on the size. Probably. I was talking with a rep a while back and he said they could try building something if you could come up with a schematic.

Doubt they can do it with the RGB, but it may be some useful info to somebody with deep pockets here.

Expenses are relative matter, after seeing people paying 1500 USD for bare 488nm diode or 1300 USD for Linos BE.

Of my point of view 1056 for 800mw RGB / 1700 for 1.8W RGB with such RGB beam divergence sounds very reasonable.

You're right. For me it is expensive, but they are high quality so I can understand. My finances wouldn't allow it at the moment, but I do want a Kvant module in the future.
