Would I need goggles for a 0.5 W blue pointer? And what about LaserBTB not having a 5mW green -- should I just buy one of those elsewhere?

Not into building my own ATM. I'm building a quadcopter and the number of headaches with it is mounting, and work and ... well, at this point, easier to just buy for me. :)

Hi all! About a year-ish ago, I was on here as a n00b and in the end I got a set of R/G/B/V lasers, pointer-style, from LaserBTB, all 80 mW. The idea was to have a nice set of same-spec'ed pointers to show off and to also use for astronomy stuff and photography and to show how horrible the...

I've been told that the legal stuff and the general process isn't hugely accurate. An ADA friend of mine actually told me that the most realistic is the movie, "My Cousin Vinny." At least with Colorado judges.

I recently bought my first lasers in half a decade based on advice on this forum. I don't have much to contribute so didn't think I'd be back much, but I run a blog where I discuss misconceptions/conspiracies/etc. related to astronomy, physics, and geology. I've been watching all the old Law &...

Good to know about the noise. Weird to know about the eye's reaction to the violet pointer. Regarding the quartz, it does not do this with my other quartz crystal. So, I'm thinking that it's an impurity that's fluorescing. From this page, it looks similar to the color of some of the minerals...

I e-mailed them 70 minutes ago. 5 minutes ago, FedEx showed up with the lasers. Observations (bad): Cases/lasers were slightly dirty, as in, after handling, my fingers were slightly blackened and it looked pretty gross when I washed my hands in the sink. Blue and violet lasers has a very...

Unfortunately, no. After my foray into this stuff three weeks ago, I thought one would be good to have. Then I saw that they start at a few $hundred and changed my mind.

Oh yes, green'll be used the most. But the others are scientifically informative. And fun ...

Yeah, sorry. Placed my order for the 80mW violet, blue, green, and red lasers. I think a great demo to show during open houses would be how poor our vision really is in terms of an uneven color response.

Alright, I'll e-mail tomorrow (on iPad ATM). Looking back at this thread, I placed the order Nov. 10 and was contacted Nov. 12 with the acknowledgement. The payment came out of my bank that day.

I have not yet received the pointers. In fact, we're still on the "Paid" stage of the order process as opposed to "in process and production" which is supposed to take 3-4 days. I figured I'd wait until perhaps Friday and if not updated yet, I'd contact them.

Just got this e-mail from Kevin:

Okily dokily, placed my order for the 80mW V/B/G/R on LaserBTB. I also used the 10% coupon code on this site that paid for half of shipping, and put a note on the order that I heard about 'em through here and to please double-check the output before shipping (their 80mW they claim is 80-90 mW)...

Thanks. Though apparently I left out an option -- Lazerer is apparently enjoyed similarly to LaserBTB on this forum, and their lasers look similar to Laser BTB except that I actually can't find weight and size specs on their website. But, 100mW blue is $90, 100mW violet is $40/$50/$43...

Okey dokey, after some other work, back to this 'cause I can't sleep right now. Here's what I'm looking at based on the links to companies you provided: Optotronics: All I'd get from them is a 100 mW green pointer (with special caps!!) for $140. Seems overpriced. Dragon Lasers: Looking at...

Thanks. That's still on my list to look through and really evaluate, but the keys are a negative for me. Might be something I just live with, I need to decide that against what other options there are. One our observatory had was a pain in the arse where you had to have two different keys and...

ApexProxy - sorry, I didn't see your thing about pen-versions 'cause you added it after your initial reply. My main use would be for astronomy -- pointing out stars and constellations in a semi-light-polluted area to a class of 50 or so requires no less than 50 mW and it needs to be steady...

Okay, so let me see if I have this right ... these days, some shady folks will advertise "5 mW" laser pointers in order to get around some rules, but while they're labeled as such, they're the CPU-equivalent of overclocked and can be much higher power. For $5, might as well try, hence the eBay...

Thanks, but I'm a bit confused now. Laserpointerer, the link is to 5mW-rated pointers for ~$5, but people are saying it's brighter? And same with your links ApexProxy - they're 5mW but you're saying they're 12-18x more powerful?
