Just got my new project going tonight . Made a 1W IR Labby using some diodes I acquired from Chris.
Im using a Meredith Module to colllimate the 9mm diode. As you can see from the video Im getting about 1.17a's thru the diode right now measuring across a 1% 1ohm power resister
Im viewing this thru the viewfinder of my Nikon L18 camera.
I have some questions.
1.) Right now It will burn great close up maybe 75 mm away. But at two feet will not burn anything as shown on video. I am now learning about multimode laser beams. Ah... I am only a grasshopper.
2.) What kind of lens can I purchase to focus the beam to a pinpoint at a great distance away from the emitter.
