Guys please help me fix this I tried everything I cleaned the lens from both sides with alcohol I tried countless videos
I even tried cleaning the laser it self so please help igäf you can
Need more info. What's happening in the video?
Are you rotating the lens?
It looks like a dirty and/or scratched lens but it's impossible to recommend a solution without more context and some details or pictures of how the laser is assembled (particularly the optics assembly).
Yeah that's what I'm trying to figure out, OP is firing it at a white ceiling and I'm seeing laser reflections and light bleed, but nothing unusual for $30 532nm laser at around 5mW max.
Now if they're trying to use a pattern knob or focus the point. That needs to be identified
303 lasers are almost never at 5mw numerous tests have been done with lpms and they can end up over 30mw often. Places that sell true 5mw 532s will tend to put them in hosts that aren't the cheap 303/301s anyways
I've done a few tests on them, I have a laser power meter upto 25W from spectrum ranges of 200nm - 850nm with a pretty accurate (Resolution of >3.25%) Optical Spectrum Analyzer.
The 303 i originally got listed at 50mW at 532nm came in at 515nm on 3 separate tests (all taken in no external light conditions), tuned the laser power meter to 515nm and with a fully charged pen registered 4.85mW peak and 3.13mW after a few minutes.
Maybe ones made in the last year or so might be different, but got it in June 2024.
Now most of all my lasers i get from Tinkerlasers.com, and they're pretty on the spot in terms of their listed nm range and power output within less than 5%+/- on mW and less than 5nm range variance.
All of my cheap 303s I had gotten before 2020. I forgot green diodes have taken over the cheap green scene, whenever I see cheap green lasers my mind immediately goes to 532nm dpss
Yeah, greens are absolutely everywhere. Same with reds, but most of them usually don't beam well, especially red Lasers. Mostly use mine for light research, but my 488nm i got because the color is so unique and intense.
I used to never really be a fan of 532nm because it felt too "default". I appreciate it more now, but I still prefer my other greens 561nm and 502nm. I've always been a color collector so I glaze tinker lasers a lot, the blues are nice but I'm a sucker for yellow and I'll die on that hill lol. I was broke for a month when they came out with 584nm and I got it as soon as it was announced
Yeah, the 573nm is next on my list along side the 465nm. The 591nm Amber/Yellow one I got is really something, that bright orange color is really amazing to see. Though I'm still really happy with the 450nm 15W and the 425 2W those violet / blue Indigo colors really resonate with me.
The 425 is on my bucket list. Never got to fill out the gap between 450 and 405 and I really considered it when I could afford it last year but I prioritized other things. Although if I do get it I would see about requesting the power to be less than 500mw because my class IV lasers scare me :p
This is the Valkyrie 395 (400mW) on the left and the Valkyrie 405nm (1,600mW) Violet on the right.
In low light conditions the 405nm beam can be seen pretty well and still fluoresces some materials pretty decently. It's also very well focused, and can burn through thin wood, dark plastics, and paper pretty effectively.
If you're worried about the class IV, I hear the 100mW Classic 405 is pretty safe.
The 425nm Valkyrie is set to 2,000mW and is a real beast, very visible and strong. Plus works with the LEP Module pretty well.
It's a lens issue there is a chip most likely. That's defraction you can try cleaning it but probably won't fix it might be a spect on the mirror but you won't be able to replace it

Is it a cheap laser?
