Yeah it depends I guess everything I've read about rayfoss was good with few exceptions. If you don't cone to trust rayfoss try o-like that's another popular one. And I'd nothing else order parts and learn yo build one I'm currently looking to do that myself with one of jayrobs kits.

I hope that's true!

I still need to convince my dad to let me get one of these, I want one so badly. haha... I'm waiting for the perfect moment. :D

Also, I've read a lot of bad reveiws about rayfoss with bad lasers and stuff...

Thanks again.
Well. Rayfoss sells a lot of lasers, because they sell them very cheap, and sometimes faulty ones slip through their QC (if they even have one). They also do honor their warranty, but you have to pay for shipping (both ways) if you get a dud.
Most would say the quality is not anywhere near the pro's like CNI. But a decent laser at a low price is worth it. :D

50 mw will not burned, unless it is REALLY over-spec. youll wan to go for 100mw or more, preferably more. but with great power, comes great price, oh and great responsibilty (because youll need to get goggles, because you can only fuck up twice)

alright, I think I'll take my chances with rayfoss since I'm saving the rest of my money for other things. I think either this one: www.rayfoss.com or this one: www.rayfoss.com is what I'd like to get.

I can't seem to find where they sell googles on rayfoss, do they sell them there?

they dont show them on their website. i simply asked her for them. havent seen them yet its only been like 9 days since i ordered from them. ii waited a month and a week for my laserlands laser.

oh and if burning power is what you seek dont go for the pen type, get a focusable torch.

okey, thanks again.

I'll try to convince my dad today to allow me to get one. :D

and just out of curiosity, has anyone on this forum gone blind in parts of their eyes?.

I haven't admitted this, but I have a 'spot' in my left eye -- and it wasn't even from a laser. It was from a high powered blue narrow-angle Nichia LED in 2002.

I was looking at the die itself under a loupe, to observe the color changes/differences (green vs blue) at barely-operating threshold currents. Bumped two leads of a pot together and it went full power for maybe a second.

Saw a pink spot for a month. It's since turned black - but sometimes when I'm tired it's a pink speck again.

... Keep in mind, this wasn't even a laser. This made me a believer. You can be as careful as you want -- it's the mistakes that you can't even comprehend that'll get you.

Goggles on, then laser on. Laser off, before goggles off.

I also take these precautions:

-Non-FDA compliant lasers are in a lockbox.
-They are stored without batteries. (I have seen Dildas and o-Like new styles turn on, if batteries are in, when unscrewing/tightening the endcap - EVEN if the button isn't pressed)
-Focusable lasers are stored DEFOCUSED, I widen the beam as far as I can before storage to minimize damage if an accidental illumination does happen.
-FDA-Compliant lasers have the keys stored *Separately* from the laser itsef (again, batteries out.)
-If possible, goggles/glasses of the appropriate WL are stored WITH or NEAR the laser itself.
-Each portable laser is in an anti-stat bag as well -- this is not for the laser's protection, let me explain:

The lockbox, storage without batteries, defocusing, and individual statbagging of my portable lasers serves this purpose:

** To make sure that I am _thinking about it_ and _aware_ and _present_ when I am going to turn on a laser. **

The point is to make operation of the lasers as 'non casual' as possible. I have to open a lockbox. I have to remove it from the stat bag. I have to insert the batteries, turn it on, and focus it. (In the case of FDA-compliant, I have to insert the batteries, insert the interlock, turn on the key, open the shutter, and wait 5 seconds.)

This may be annoying to some people, but the procedure required gives me some time to think about an realize the seriousness of these instruments.

Maybe it seems paranoid - but the "LED incident" is what made me decide to not play around with this stuff. It may seem like overkill but I got a "taste" of optical injury, and I do not want more.

Once you get a little, it changes you. I know many people who say "I'm careful - I won't make a mistake."

The point is, most mistakes and accidents happen (not only in lasers, but in HV electrical, construction, etc) when experienced, knowledgeable people think that they "know what they're doing" or have "done this a hundred times without a problem". They get a little lax, or figure they've done it so often tha they don't need the protection. And then "Shit happens" and they aren't protected. And they get injured or worse.

So, yes, there are folks here who have optical damage. I didn't expect it, and I thought I was being careful. From what I understand, I'm not the only one.

(I heard some horrible story about some guy passing a laser into his eyes and seeing 'black spots' when he did it - and then doing it again to 'see if he really saw it' or not... and then again because he 'wondered what was going on'. Each time he was doing that, the black spots he was seeing was him burning his retina. Permanently.)

great system, kinda like a safety checklist. you do have a lot of high powered lasers or lasers with color more potentially damaging than others. keeping up with all of those goggles would get hectic and would need at least 5 to 10 seconds to check to make sure you are fully protected.

I'm so sorry about your accident. And thankyou for sharing this, though. I will wear protective googles at all times when using a laser from now on... when I get one. And I won't let my friends use lasers unless we both/all have protective goggles and it's not a party or something like that.

I think I'll be very, very cautious... because I certainly don't want to go blind, or even blind in a little spot because I have other hobbies that involve looking, a lot. Like photography.

Thanks again.

Oh man... ouch!

I'd bet that LED was just as bad, if not worse than a laser. Those emmitters can easily create 3 watts of optical power and if you focused it right onto your retina then I'd bet that at least 50% of that tagged you right where it hurts. That was hard to read for me because I've done that before. Not blinded myself, but observe LEDs right when they start to illuminate. Man that is stupid! I'll think of this post next time I play around with them.

One really stupid thing I did when I was a kid was look right at a camera flash as it fired. I saw a red haze for hours, but I recovered.

It's concerning when you've got dangerous hobbies. I also build high voltage projects and Tesla Coils and I am very careful not to get bit. If you're exposed to dangerous voltages and lasers constantly, either for a job or hobby, it's likely that even if you're careful you will get tagged. I got shocked by a 440v capacitor with one hand one each terminal. The current went around my arms and torso. It was the most intense feeling I've ever felt. Getting bit on one hand is one thing but when the flow goes through your whole body... yeah I can't even describe it. I was shaking for 20 minutes.

Now with these >500mW 445nm diodes it'll be so easy to get blinded by shining the laser at a door knob across the room. It's not just a matter of not looking down the beam, but more of not using it in the house anymore. If you gaze at the wrong spot at the wrong time while the laser reflects... then your most important sense will be damaged for life.

I am for sure buying goggles for my FLX. I had a cheap green laser at 5mW which was so bright it made my eyes tired just pointing it, it definately seemed over-spec. Nonetheless I'm not willing to gamble with my vision.

Remember: If your FLX is not coming with an IR filter, you will need multi-wavelength safety glasses to burn safely (without potential eye injury from the +25mW of IR).
I have these: Multiple Wavelength

Cool, thanks ill check into those also. I mostly love to see a bright beam in the night sky. Burning things seems fun but i've seen plenty of youtube videos of it to be only mildly interested.
