It hasn't got to light up a large area it just needs to be like a tight spot say a5 foot circle at 40 to 50 yards the illuminators on the market are about 150 pounds an I have built a few lasers an thought it would be a cheap alternative all the best ADE

Any body ?

would these gogles be suitable for building my 100mw 650nm red laser Complete protection from 600nm to 700nm. Visible light transmittance: >55% Optical Density: > 5.0, (OD +5, OD +6) Attenuation: (10-6 < N% < 10-4) thanks for any info atb ade

thanks for the warm welcome people i am very interested in lasers but after reading alot of the safety i am a bit worried about damaging my eyes after reading alot of horror stories of slight exposures leading to eyesight problems very quickly i have purchased a rohm 100mw red diode 650nm cw...
