Smallest RGB unit you know of?

Hey there, im looking for micro RGB dichro combined laser modules to build into a handheld unit (yes i know, eyeroll), im wondering what’s the smallest easily available units you guys know of? other than the standard units and specialized micro units for personal eyeglasses displays, i don’t see much. Any leads would be greatly appreciated. worst case i’ll need to get handy in CAD and find somebody with a 3D printer, but a pre made compact unit would be awesome if available. thanks pals!

Hey! (Welcome BTW!)

Have a look at the pico projector RGB modules.
I think they have around 200mW.
They featured a 80mW OPSL 530mW laser with a sm red + sm blue diode.

They are tiny! Smaller than a zippo lighter!

They where available on eBay for a long time. I can’t find them currently :frowning:
Might be that someone has a few left (@Laser_Project?)

Otherwise the smallest and cheapest are the RGB modules available at eBay/aliexpress.

If you got a 3D printer, Arctic got you covered with a build with of the shelf parts:
Arctics RGB host

Otherwise, nothing beats going custom but that requires tools (mill, lathe).

Lasertack also offers small rgb modules but it’s cheaper go buy the Chinese modules.

those pico projector modules would be perfect! unfortunate i can’t find them either, but that search term does help me and i found some new sources. Man is that CNC build sweet, i would love to do that if i had the tools. Arctic’s open source project is awesome and may be just what i’m after! Thank you for the info!


Sad that these modules are not available anymore.

I would recommend searching for pl530 or „rgb laser module holography“ on eBay.

If I remember correctly he advertised it as holography friendly.

The seller was private, so he might just have the modules not online currently.

Better late than never? Maybe not in this case, but this might be the ebay seller who had some RGB’s listed in the past. Or, maybe I have him confused with another seller because I thought he was in Seattle, this seller isn’t.

I added that second photo searching the completed listings, maybe he moved to NY, this is the seller who had them.

@Gabe - Smallest that I know is Exalos RGB module 30mW (4.4mm x 4.2mm x 2.9mm)

Second smallest is Sumimoto RGB module 150mW in DIP module.

Seems that Osram has Vegalas RGB module (7.0 x 4.6 x 1.2 mm)

The seller just listed another one of those small Green OPSL lasers with Red and Blue single mode diodes: White Light Laser Engine RGB Holography W Green OPSL!! | eBay

Edit: I had emailed him on ebay asking if he had more due to Gabe’s post here.
