Default Why so cheap?

Why are these diodes so cheap?

Good question.

300mW of IR is not that much. He might of pulled them from cheap PHR sleds. PHR sleds are <$8 in bulk, and he is getting $3 shipped for these diodes, so he can make a profit on a normally useless diode.

Default Re: Why so cheap?

The only way that I could see buying such a low powered IR diode laser would be as a transmitter for communications experiment. Also maybe you could buy a handful(10) since they are cheap for an array to increase your total output to 3000mw which would be very powerful. There isn't an easy way to combine the power optically though as far as I know.

How did you mount the 5.6mm can in a 9mm hole??? Also how do you get 300mWs of IR to produce 100mW of green? Or am I missing something?

My pointer had a 5.6mm mount. It had a round nut in back and all you had to do was decan the diode and put it in place then screw the back in.

As for 100mw some was probably IR so i would guess ~65mw green ~ 35mw IR

I suspect there was LOTs of IR included there. That's ok though.

Lasers that emit at two lines at once are special.

You can call it a "multi-line" pointer.

Two in one!

I bought one from that seller and it made green for me so it should be near 808

Because they were probably made in china and they bought in bulk most likely due to some defect possible printing or similar. Also because the probably only cost them about $0.10. At least that is my experience when I have had things built in china. They can make entire PCB assemblies for less than I pay in parts.
