I just picked up a bunch of these yesterday, they are cute little 3.5mW 670nm modules from Melles Griot. I don't expect that any of you would be interested for the diode in it, but the optics are a true gem. First is a nice glass acromat followed by a large pair of anamorphic prisms, these shape a square beam into a round beam. All the optics are coated for 670nm so they would work perfectly with a DVD burner diode. As for the electronics, the module uses a 5.6mm can held in by a plate that is screwed down, there is a temperature sensor and a TEC on the laser diode part. I would guess that someone here with better electrical knowledge could easily make a driver board and temperature controller for these.
I don't know how much these are worth to you but I am open to offers!
