Just got a single mode 650/660nm laser. Uses one of the open-can LPC diodes. Amazingly tight beam. The divergence is insane low! Using the lens on the left which I don't know what kind it is?....(on the right is a 3 element lens for comparison). Anyone know what kind of lens is on the left? The dot also has a line running through it....
I can really appreciate the beam quality for these diodes, they have got to be among the best. Even across my apartment, focused at infinity the dot is soooo small. I'd estimate 0.5-0.6mRad.
