I may want to put together a GB on a few diodes if there is enough interest. I would like to get a few more and I {WE} could possibly get a discount...more so than shipping in one tray. Let me know...they are C mounts and are all over spec from what I have tested of 4 in use. The raw output is always above 220mw, but is spec'd at 200mw and all have individual test sheets from the manu.They are NIB. They do NOT have a FAC lens installed. I have made a fixture to align the diode to the lens material and fix it in place with UV adhesive. This is not for the faint of heart or first time try at it. I had to learn though. Cost me a diode. I am not going to install lenses. It is a real booger to say the least about it. There are many other options to collimate much easier. I am simply trying to get a good deal on a few more and to help PL only. Lets just see who is a die hard right now.....that would include someone that is willing to build a driver for it and make a mount and lens assembly or just implement it into a broken or dead laser housing. They will survive w/o a TEC, but it makes them much more stable and highly suggest using one. Single mode with a 150um stripe width.
