Just my opinion, but I would think just using a LED (from the color you like and have it very dim, either suspended in an empty room with no small reflection or pinned on a dark and light absorbant curtain) would be more efficient than a laser dot. To explain my assumption, I take that you like...

Thanks Encap, again a good ressource :) Those host are interesting :)

Hi Guys, I was wondering if any of you had already worked on CNI's host? http://www.cnilaser.com/PDF/GLP-532.pdf Are they easy to dismantle? can they host 12mm modules? any feedback about heat dissipation compared to other pen host? I know they're not in trend anymore, but I loved mine and...

That greenie host is gorgeous! wow :love: more details about it? Anyway good job :)

Hi Tung, I might be interested by the pocket green or pocket blue. Do you measure power output with the 3E lens? does the blue have 3E lens as well? and might be a newbie question here, but how does those diode support that power in such a small host?

Thanks Encap, I understand my confusion between brightness and illuminance, and I'll add that my assumption of being able to find out the brightness and be able to standardise perception is way too simplified here, as angle and distance of the visible beam would be the most important thing to...

Hi, thanks for your reply. Indeed, that is why I stated "hypothetical 532nm single diode" I don't think I am mixing physics, as Brightness is still a physical specificity that can be measured as illuminance. I was not asking about subjective perceptions there, I think you understood this as...

Hi guys, Tl;dr : How important is it to consider beam thickness and divergence for a similar powered laser if we want lots of brightness/visibility. -------------------------------- More context : I'm new to single diode laser, and searching I'm trying to understand more. With DPSS 532, at...

Thank you all for the warm welcome! :) Thanks RedCowboy for your interesting post, to me laser have always been about the beam specs over power or wavelength. Thin, perfectly round with gaussian dot and the lowest divergence possible. Then of course to appreciate it, the more visible it is the...

Hi there, I guess I can present myself after lurking for a while. I've been a laser enthusiast for a long time now (use to collect red pointers in elementary school 25 years ago...) I'm glad I went through my childhood without becoming blind tho, oh how stupid we could be back then (yes I did...
