@hakzaw1: LaserFreeks? sorry but never even heard about it :D

about the glasses, 500? I think that's a bit too much for me :)
I better go with 2 pairs a bit cheaper ones

>>>> HERE--Protects all visible wavelengths BUT SPENDY

100-20-260 laser safety glasses for use with multiple wavelengths: nitrogen laser, 337.1 nm, eximer laser, 193 nm, 248 nm, 308 nm, 353 nm, helium silver laser, 224.3 nm, neon copper laser, 248.6 nm, krypton laser, 416 nm, Dye laser, 390-435 nm

THESE..
Laser Safety Filter 260

OD Specifications:
OD 7+ @ 190-540 nm
OD 2+ @ 630-650 nm
OD 3+ @ 650-690 nm
OD 6+ @ 690-1330 nm
OD 8+ @ 1064 nm

--to save some $$ (but less OD protection)
you could get two sets cheaper that will cover all 'colors' ..

just be aware of side hits-- a beam could go over one's shoulder and reflect into your eyes from the inside of the lens--it almost the same as a mirror=---when you think about it. so side shields are important.. welcome
Cool, thanks for sharing. I'll take a look on them later. However seeing the specs you quoted VLT will be horrible I guess. Still they do not protect against 589 nm, so I need second glasses anyway.

SQunX: Also considering green 303 I assume it is 532 nm - be careful as these might not be IR filtered. Even the IR has different beam characteristic, it might be dangerous for prolonged exposure at close range even with glasses on (if not covering IR). I mean if you are trying to burn something or shine it on something more reflective.

Yes, the green one is advertised as a 532nm.

Uhm another question. Have anyone a recommendation for a driver for my lpc836 diode?
Because I don't want to fry it right at the beginning.
Are one from a chinese ebay seller okay?

maybe this: 300-700mW 638nm 808nm 660nm Orange Laser Diode Driver Power Supply 2.5A Output | eBay

or this one: 1pc 0-800mA Oclare 700mw Orange Red Laser Diode LD Driver Power Supply 3v-4.5v

its hard for me to find a driver for this power range that isn't too expensive
Welcome SqunX. That's a touchy diode. Case negative if I remember. I've killed a few learning the hard way. Luckily they are cheap. Get a quality driver. You can always repurpose it to another diode. The nano drive might be a good one. You will need a test load and DMM to set a driver with a potentiometer. The custom Google search bar on the bottom of the forum page works well.

That's the problem with using a 808nm diode (case positive) drive with a case negative diode. You ABSOLUTELY have to isolate the driver and diode from the case of the host. If you can do that, they will work. I think it was Pman who used the drivers from cheap 532nm modules from Fasttech to drive LPC diodes.

Welcome to the forum. :)
Yes, do be careful with those 303's. They most certainly put out more than 5mW 3D!

Finally my 303/301 Lasers arrived last weekend :)

(but im still waiting ​for my lpc diode)
