Hello, I bought these glasses: Laser Protection Goggles Safety Glasses for 808nm 830nm 850nm IR Infrared Laser | eBay To protect my eyes from a 5W IR (808nm) laser diode. Am I allowed to shine a dot through the glasses, to check (with a camera) if it gets filtered out? Or will doing this...

Hello, I want to create a linear current regulator for this IR diode: http://www.eqphotonics.de/cms/cms/upload/datasheets/WSLD-808-005-3.pdf It's a 5W diode, operating at 2.0V at about 5A. I'd like to make use of a linear regulator, powered by a 5V, 8A switched mode power supply. (link) The...

Hello, I recently ordered laser safety glasses on Ebay for my red 635nm laser. (this one) But when I shine the laser trough the glasses, the light that comes out is Brighter than the reflected light. ?! this means that more light passes trough than gets blocked. The dot is still so bright...

Hello, I was scouting Linear Technology's ICs to find a switching regulator which regulates the output current, as required for laser diode drivers. (alternative: Maxim Integrated) Preferably I want a regulator which doesn't need an inductor to operate. I read that charge pumps might be what...

Hello there, Problem: I bought a Mitsubishi ML520G71 laser diode (red-orange 635nm; 300mW) but I can't seem to focus the beam to a small dot. I am aware that it's normal for the laser pattern to be a line. However it should be possible to make this line-shape very small right? (let's say at...
