Just ordered a 20mW 405nm Laser from Aixiz

Pretty excited as it'll be my first non red or green laser. Anybody bought one of these before? Any tips?

I have the 15mW 532nm kit from aixiz too, it seems pretty overpowered for its supposed rating, I'm hoping to find the same from this new blue/violet module. My 15mW can burn electrical tape nearly instantaneously and can light kitchen matches with black marker on them. I'm wondering if I'd blow out the diode if I tried the 5Volt power supply from my 15mW on this laser instead of the 3.2V its supposed to use.
 





I was experimenting with my 20mW Aixiz 405nm and I was running off a 5.5V variable wall unit consistently. This was after turning the pot all the way up, too. 17 bucks makes it easy to risk. I was able to light red matches no sweat. In short runs it seemed fine. I actually ran it up to 12V+ with an accutely noticable change in brightness. I then killed it by starting it on 12V rather than gradual steps. It would have keeled in a short time anyhow but I think it was doing pretty swell on 5.5V. The add actually stated 3.2-5V but the paper with the module said
just 3.2V.

I would not advise this unless you're willing to lose a few bucks.

Very true, the relative low cost of the unit itself makes it less scary to mess with. I'm curious though, where was the POT on the unit, the photo makes it look like a brass barrel w/ two wires coming out- does the barrel hide a driver w/ POT on it? If so how easy is it to get to it?
 
Unscrew the module. :D

That's all there is too it. I have to replace mine as well. I won't be running 12V sessions with it next time. :D
 
i just got one. looks very dim to me. i think i might crack it open and check it out further... no LPM but i doubt it is pushing 20mw.
 
Don't be fooled! 405nm is VERY dim! 100mW doesn't look like much. Aixiz doesn't sell underspec.

As Synchros pointed out, 20mW of 405nm will appear VERY VERY dim.

To most people ~100mW of 405nm appears about as bright as 5mW of 532nm.
 
why?

horizontal axis = laser λ (wavelength) in nm
black vertical axis = photopic sensibility ('eye sensibility in bright conditions')
green vertical axis = scotopic sensibility (dark conditions)
 
Do you see where 405 would be on there? Right at the bottom. Look at 650 as well.... Not the bottom.

You have two scales there... daylight and lowlight. Imagine the 532 line being 10mW, and the 405 line, at night, would be way(!) dimmer by comparison! Daylight conditions are WAY more abysmal for 405 and 650 as well.

Hello could you please let me know the terminals on the laser diode.I bought one such laser and I am not able to get it running. It would be great if you can post a picture of the back of the diode and the pins labeled. The diode that I am using is this:
Wholesale Free shipping Laser Diode for PS3 KES 410ACA (3 pin) video game accessories

I am hoping it is either the aixiz 20mw blu-ray diode or the sony sld3131vf.
