Never look into that beam. Because of the way green lasers work, that is actually Infrared light that is much more powerful that it appears, more powerful than the green laser was originally.

Well, I'm definitely open to suggestions. I liked the pens because they were small, looked nice, and most of all very cheap. As for the 405, I don't really care that much about how great these lasers appear (It's just my first build), but will it still be able to cause white objects to...

My goal is not to have the lasers, but to have built the lases. I want to get some experience in DIYing and yet not waste to much money if I screw it up. And since the lasers be 5mW or less, I can show them off to my friends as lasers that I built myself.

I wasn't sure exactly where to put this thread so I'm putting it in general. I've decided I want to start my first build in the next couple months and decided to start by getting some advice here. I want to build a rainbow of 5mW pens. I have been looking at parts such as these: Laser Pointer...

And they burn so well :D

As I said in the title, I know there are a bunch of reviews out there for this laser, but since it is my first laser, I wanted to review it myself. The laser is a great laser overall, I don't have an LPM, and I have no other lasers to compare it to, but it is probably around 400mW since it...

I'm no MacGyver but I think I've found a temporary solution. If I wear both pairs at once, I get what you were talking about: Its kinda dorky and is a pain, but it will work until I get a new pair of glasses

I recently purchased my first laser: O-Like's 400mW 405nm (Power Rock 400mW blu-ray 405nm laser torch/adjustable/waterproof), and plan to do a review of it soon. But first I have a question to ask about glasses. With my order I bought two pairs of O-like's 405nm,450nm,473nm,532nm laser safety...

The high school I attend recently put on an astronomy night in which a few teachers brought telescopes and students could look at stars, planets, etc. A friend of mine had brought a <5 mw green laser in order to point at stars and to play around with. He ended up letting some friends borrow it...

Hi I'm a laser newbie and stumbled across this forum while researching. Ive spent a lot of time here in the last few months just got around to creating my own account. I plan on starting my first build soon (if i can find the cash). thnx for reading
