OP - I have one of these Sanwu RGBs. I would equate it to an iPhone. It’s an excellent product, insanely good build quality, but a bit overpriced for what it does. It’s definitely a feat of engineering though. I’ll be making a full review on it soon...
I just received my Sanwu RGB in the mail today... pretty incredible. The white feels much more ‘real’ than either of the chinese rgb modules I have, and the alignment is much better too. Going to make a review if I have time.
I've got a pretty cool laser up for sale today, a multiline HeNe that I bought about a year ago.
I hate to let it go but it mostly just sits around in a box all day and I have no real use for it.
It measures 5mW on my LPM, and as you can see it outputs all four orange HeNe...
I’m willing to purchase any laser that was manufactured by Changchun New Industries. Basically any CNI pointer/handheld that you’d like to let go of. PM me if you’re interested in selling. :)
It’s a $70 Thunder Optics piece of crap, so it’s not too accurate, but it’s good to within 1nm usually. I calibrated it specifically for this range (using 532 and 589 as reference points.)
And 565 is very greenish yellow, it’s surprisingly similar to 561 though.
