MolecularMan14 Posted November 21, 2004 Posted November 21, 2004 Ive got a quick question. I was thinking about buying a green laser pointer. Are they really that much better than classic red ones? If yes, how so?
YT2095 Posted November 22, 2004 Posted November 22, 2004 no different in all honesty, it`s just that our eyes are more sensitive to the green part of the spectrum than the red. it only `Seems` brighter, infact the wattage is the same
5614 Posted November 23, 2004 Posted November 23, 2004 well, they are cooler, i was gonna get one... also, due to the shorter waves length, you can see the green beam which looks cool. they are the newest part of technology, and expect for the price are good buys, (if you like that kinda thing) YT (on IRC) said that when red lasers came out they were also ~£40 and now they are ~£10, green lasers (on e-bay) are ~£40, so he thinks that the price will come down in a few years, but you may as well just buy it now! they also have vastly longer shining distances. go to e-bay for some cool pictures
5614 Posted November 23, 2004 Posted November 23, 2004 CO2 lasers are cool, but are not really in the same category as hand held colour lasers..... i mean, ones a tool ones a toy, ones harmless (except shining it in people's eyes) and the other is well, a dangerous tool! nothing wrong with dangerous, just when it comes to what you'd rather have, green laser pointers and CO2 lasers are quite different things.
boris_73 Posted November 23, 2004 Posted November 23, 2004 i thought the lasers were illegal in Great Britain, because they caused to many accidents eg damaged eyes ect
5614 Posted November 23, 2004 Posted November 23, 2004 nope, i dont think that they are publically sold often, however they are not illegal, just not recommended, or some crap like that! im sure they're legal though.
Lance Posted November 23, 2004 Posted November 23, 2004 I think that in some places over here you have to be 18 to own (or buy?) laser pointers.
5614 Posted November 23, 2004 Posted November 23, 2004 from: http://www.nrpb.org/faq/laser/laser8.htm There is no specific legislation covering the use of lasers in the UK. However, general safety legislation will apply, such as the Health and Safety at Work, etc Act 1974, the Management of Health and Safety at Work Regulations 1999, the Provision and Use of Work Equipment Regulations 1998 and the Personal Protective Equipment at Work Regulations 1992. A suitable and sufficient assessment of the risks from the use of the laser should be made by the employer. Lasers used in domestic equipment will be required to comply with the Trades Descriptions Act 1968 and the General Product Safety Regulations 1994. Any products sold as toys will need to comply with the essential safety requirements of the Toys (Safety) Regulations 1995. Compliance with the current British Standard on laser safety, BS EN 60825-1:1994, is required under European Directives for many laser products, including those operation at voltages in excess of 50 V. about the company: http://www.nrpb.org/about_us/index.htm
MolecularMan14 Posted November 24, 2004 Author Posted November 24, 2004 well, I just bought one, for under $50, so Im just waiting for it to come by mail
5614 Posted November 24, 2004 Posted November 24, 2004 wicked, i really want one, but i doubt i'll get one. if you get any cool pictures (like long green beams in the dark) post em somewhere!
ydoaPs Posted November 24, 2004 Posted November 24, 2004 50 bucks? u got ripped off. you can buy them for under 10 at pretty much any fair or carnival.
5614 Posted November 24, 2004 Posted November 24, 2004 nah dude, this is a green laser pen, costs about £40 (UK) so for pressumably $50 (USA) that sounds quite good. (the £40 (UK) comes from e-bay which is cheap anyway, sounds like a good buy to me)
MolecularMan14 Posted December 5, 2004 Author Posted December 5, 2004 well, I just bought one, for under $50, so Im just waiting for it to come by mail Just an update, I got it a few days ago (finally ) but it's awesome. In the dark you can see a cool beam, and I'll try to send some pics soon. Its extremely powerful! I honestly cannot believe the distance and power of it. I may have scared some of the neighbors a few blocks. It's intense!
5614 Posted December 5, 2004 Posted December 5, 2004 told ya it'd be wicked.... cant wait for the photos... so no pressure dude!
MolecularMan14 Posted December 5, 2004 Author Posted December 5, 2004 My cam is @ isnt here at the moment, so I'll get 'em to ya in a few days (probably tuesday or something)
5614 Posted December 5, 2004 Posted December 5, 2004 ok man, it'll be worth the wait (for me anyway!) woa.... green laser pics coming up... where did you get it from? (if net, which site?)
Sayonara Posted December 6, 2004 Posted December 6, 2004 The GMT line in London is illuminated at night by a whopping great green laser. Very pretty.
MolecularMan14 Posted December 8, 2004 Author Posted December 8, 2004 Ive got my camera, so now Im just waiting for everything to get very dark (so you can see the beam well) I'll have them up soon
MolecularMan14 Posted December 8, 2004 Author Posted December 8, 2004 I tried to draw some squiggles on the walls to show how powerful it was. Good thing my camera can do that! They came out pretty cool, especially the one I did in the steam room (#3) I love the beam from the thing! Enjoy!
Sayonara Posted December 8, 2004 Posted December 8, 2004 You might want to think about cropping the dead space from images in future, seeing as you have a limit on what you can upload.
5614 Posted December 8, 2004 Posted December 8, 2004 from those pics it doesnt look like you can see beam too well... in real life ie. not through the camera, can you see the beam in a normal room (assuming it is dark)??? or do you have to be in a steam room? what power rating is your laser???? 5mW?
MolecularMan14 Posted December 9, 2004 Author Posted December 9, 2004 Sayo- yea Im aware of the limit, but It doenst matter, they're reasonably small files 5614- the camera actually dulled the beam. In the dark, it really quite bright. But I just put it in the steam room to see what sort of resistance the beam would get from steam. I honestly am not aware of the power rating, but I would assume that since the majority of the same type are 5, so yea, I would guess 5mW. I really cant get over how bright it is!
5614 Posted December 11, 2004 Posted December 11, 2004 I really cant get over how bright it is! have you ever seen a red one? asking to see if you are saying it is bright compared to a red laser... or compared to what you thought it'd be like.
