Clint1 Posted November 25, 2013 Report Share Posted November 25, 2013 I sometimes look at gadgets and think that "I would love one of those". Laser designators hold that fascination for me but they are so ridiculously expensive. I've already got one of those hugely powerful green lasers that you can see in daylight and I thought that there must be a way of making the beam diverge so I experimented with different lenses from old spectacles and found that the prescription for 'long-sighted' works well and will diverge the beam in varying amounts depending on the strength and number of 'layers' you use. I made a cap for the laser out of a plastic top that I found, drilled an aperture, using a dremmel I cut the spectacle lenses to fit inside the cap (I found by experiment that three gave a good spread). Obviously its not as good as the real article but you can push the cap on and get a reasonable approximation and when you don't want it pull the cap off and iits back to the dot.

evo Posted November 25, 2013 Report Share Posted November 25, 2013 nothing better than experimenting, well done,,do you have any pics atb Evo Quote Link to comment Share on other sites More sharing options...
Clint1 Posted November 25, 2013 Author Report Share Posted November 25, 2013 I suppose I could take a pic but tbh its easier to get your laser and just mess about with some spectacles and see the effect which is basically what I did in the first place lol.

aris Posted November 26, 2013 Report Share Posted November 26, 2013 Be very very careful, and get specialist protective eyeware. One stray reflection, and you are blind. Quote Link to comment Share on other sites More sharing options...
Clint1 Posted November 26, 2013 Author Report Share Posted November 26, 2013 Omg, here we go, busybody/know-it-all alert beep beep beep. Btw folks don't look directly at any laser, supernova, pulsar, the sun etc. without protective goggles. Quote Link to comment Share on other sites More sharing options...
aris Posted November 26, 2013 Report Share Posted November 26, 2013 Suit yourself mate. It doesn't take much for a reflection or refraction to come back into your face. Quote Link to comment Share on other sites More sharing options...
evo Posted November 26, 2013 Report Share Posted November 26, 2013 (edited) lets be honest any safety advice is better than none because not everyone reading this thread realises the danger involved with any bright light or laser, infrared is just as bad as the light LOOKS very dim but infact is a very powerful beam and can cause serious damage to the eyes if looked directly at atb Evo Edited November 26, 2013 by evo Quote Link to comment Share on other sites More sharing options...

Red, green blue & violet you can see & look away. If the beam is collimated (focused to a spot) & close up you NEVER going to see again with any colour. Less then 1mw is classed as safe.

aris Posted November 26, 2013 Report Share Posted November 26, 2013 Good grief, are all forum led sites like this? Would you say the same about gun safety? In all honesty, lasers (partuclarly anything > 1mw) should be treated like a gun. I'm guessing by your description above that your laser is a 200mw one?

Clint1 Posted November 26, 2013 Author Report Share Posted November 26, 2013 No it's a 2000mw 445nm blue MYOB laser Quote Link to comment Share on other sites More sharing options...
landy george Posted November 26, 2013 Report Share Posted November 26, 2013 No it's a 2000mw 445nm blue MYOB laser ****ING HELL, that would cut your arm off. Quote Link to comment Share on other sites More sharing options...
evo Posted November 27, 2013 Report Share Posted November 27, 2013 don't point that up towards the sky,, you,ll cut a plane in half :lol: I use a 200mw laser when I,m gigging, and that will shine across the river Mersey which is 2 1/2 miles wide so why are you using such a powerful laser 2000mw , mine is only a tenth of that power and cost me £500 , what did you pay for it from Iran my laser comes with very strict rules of usage and must be set above head height and under NO circumstances be looked at with the naked eye ( directly looked at) surely a laser running at that power would need to be licenced . or is it you prefer to shoot already cooked bunnies :lol: :lol: atb Evo Quote Link to comment Share on other sites More sharing options...
aris Posted November 27, 2013 Report Share Posted November 27, 2013 Those 2w blue lasers are about US$600. 500 quid for a 200mw laser is quite alot! I have a 50mw green and a 200mw red - each cost under 50 pounds. Quote Link to comment Share on other sites More sharing options...
FalconFN Posted November 27, 2013 Report Share Posted November 27, 2013 (edited) I've got a 320 mW ir laser and that was £20 brand new, and that will scorch wood at 2 meters. The op was being sarcastic I think. Edited November 27, 2013 by FalconFN Quote Link to comment Share on other sites More sharing options...
evo Posted November 27, 2013 Report Share Posted November 27, 2013 its what it can do what I have paid for, over 1000 programmes it can even draw a creature on a wall and it runs round the room, worth every penny the laser itself is prob only £100 but its the programme facility built in that costs,,,well hope it is lol atb Evo Quote Link to comment Share on other sites More sharing options...
wraivi Posted November 27, 2013 Report Share Posted November 27, 2013 No it's a 2000mw 445nm blue MYOB laser Ha.ha.... sarcastic, wish I had a 2000mw MIND YOUR OWN BUSINESS laser too. Blocks to the designator. ..I'd make a rabbit swatting light sabre....also just in case the OP tries to burn me in ' arf. Quote Link to comment Share on other sites More sharing options...
Clint1 Posted November 27, 2013 Author Report Share Posted November 27, 2013 Yes it's made by the BELLENDE Co. and can bounce a beam off uranus Quote Link to comment Share on other sites More sharing options...
FalconFN Posted November 27, 2013 Report Share Posted November 27, 2013 If that doesn't make you blind it'll definately make your eyes water...... Quote Link to comment Share on other sites More sharing options...
