Yeah, that's a good point. Thanks. I followed that thread. Scary retinal bleeding... Why don't you create a new thread and ask the mods to sticky it? A "Here are the ground rules for laser use" list. If you update it from time to time, I can draw material from it.

I might end up doing that, but it's a big time sink. I've asked Rayfoss what they can do it about it on their end. In either case, I'm probably going to buy a LaserBee to make sure the lasers are classroom-ready. I know, but that might actually be a good thing. When it hits the right material...

Has your wife discovered all the cool stuff that she can do? There's tons of household objects that fluoresce awesome colors, plus some geologic minerals and more exotic phosphor materials. Some stuff fluoresces under green lasers as well, but not as many. When I go to volunteer outreach...

Hey Jerry, I want to make lasers available in classrooms because they're great demonstration tools AND a great way to get kids excited about science. You can imagine the safety and legal issues if a schoolteacher brought an overspec pointer into a classroom and one of the kids' parents found out...

I get a sinking feeling in my stomach every time I read about people getting arrested for being irresponsible with lasers. I get the feeling the U.S. isn't far from clamping down on anything outputting higher than 1mW...

Does Average Joe need to know that? I guess it couldn't hurt to put it in. Anyone who purposefully stares into a laser of any power just to see how much damage can be done deserves a Darwin Award, no? :-P

Hi guys, can anyone point me toward a cheap 5mW violet laser? I'm looking a consistent output lower than 5mW - the one I have from Rayfoss is cheap, but goes over 5mW and thus isn't a IIIa laser anymore. In particular, I'm looking for the 405nm equivalent to LaserGlow's Anser: well-built, no...

Thanks, Ferd! I'm not crazy about the price (I mean, $6/piece for bulk shipping is so hard to beat from Chinese manufacturers), but a $30 (bulk) price tag is manageable considering it's got an IR filter and probably has better QC. @Paul, I figured that it's always possible, but I don't feel...

- Lasers are fun, but they're not toys. Like nice cars, guns, and sex, they're very fun but they can do serious harm if misused. - Do not shine a laser of any power into the eye of any living thing, including your own eyes. Even if you can't see the laser dot, do NOT look into the laser itself -...

Hi guys, this may be a noob question, but I've already looked in the buying guide, and tried the search to no avail. I'm looking for green lasers that have a max output of 5mW of less (basically to stick with U.S. laws). I'm looking for value - pens that are solidly constructed and have <5 mW...

I think anyone who's serious about lasers would go through the effort to read stuff in-depth and buy safety gear. A short video is mostly pressing home the big points, hopefully well enough so that it sticks after one viewing. So yeah, very watered-down. Here's what I have so far: Lasers are...

How appropriate is comparing laser safety to basic firearm safety? Things like never pointing it at another person, making sure it's "unloaded" (batteries taken out) so kids and clueless adults don't misuse it, having proper safety gear, etc.? I also intend to talk about other tidbits that may...

Hi Lase, thanks for your response. My intention isn't to make a video worthy of sponsorship by a governmental agency or anything. I just want to take basic information that you'd put on a brochure (something like this) and transfer it into video format. That said, I have no experience in making...

Hi LPF, long time lurker (2+ years now!), first time post. I want to create a short-and-sweet video about laser safety for YouTube. The target audience comprises teachers, new hobbyists, and basically anyone with a sense of responsibility but without a technical background. I'm finally...
