My 18mw 555nm dpss is very similar, I can see the beam in daylight

Does anyone know where that module came from? I've never seen an OPTlaser or lasence module that looks like that, could there be another company producing them?

Hello! im Looking for a custom pen host that can fit a 8mm (diameter) laser module, do you have one?

im working on small 607nm modules

I saw that, they have always been making lab lasers as far as I'm aware

Wow, that is interesting, the 2 projectors I have bought both had an OPTlaser-style 20mm 565nm module

That would be a good idea

im looking for a 593.5nm laser pointer/handheld, even if only partially working, please dm me you you have one that you want to sell

ive only heard that they use 254nm lamps? where did you get that from?

The 575s and 577s got discontinued by lasence quite a long time ago

Oh, Last time someone ordered it from there they just got refunded the money

where did you order it from?

you are really getting ripped off, dont buy that, you can build a 7W handheld for less than 200 usd

Directly frequency doubling diodes is quite hard, you won’t get to good beam specs (as you said) and you need a very high powered diode, when I’ve attempted it, I used a mult-watt diode and gotten only a few mW of doubled light

$700 is way to much, you can get 7W blue diodes for $80

I am quite interested if they even use 575nm lasers in theese, the label says that It has 574nm but so far, I've only seen 565nm in these, I really hope At least one of them has a 575nm module inside

Holy fuck, 8 posts in a row

I saw that some time ago, thanks for sending it!

Those are gorgeous pictures!

I got my hopes up when the warning label said 574nm and when the listing said yellow, but it looks like it might just be 565nm modules inside these projectors.
