Wiring up a 1W 520nm NDG7475 Laser Diode Pinout

Is this the right way with the square cutout at the top, plus + (red) to the left.

Re: Wheel for Lumia

I've not read all this thread, but do you know you can make a very cheap little speed controller using an old shitty 5 dollar RC servo? You remove the PCB, replace the pot with fixed resistors of the same value, you can then PWM the driver easily to get speed and direction control over a range. ie D...

Re: NUBM05,06,07,08 and NUGM01t diodes BEWARE!y

Sorry, don't follow..maybe my poor english. Could detail more in depth pls? If I design a layout based on a given stock lens (vertically stack heigh offset, cyl distance from diode etc) and they change stock lens, my beam specs is also going to change for a given layout. Say for example the 'mister...

Re: NUBM05,06,07,08 and NUGM01t diodes BEWARE!

The beam is the same after the stock lens as it is at the emiter, ie you can always revert it back to the emitter even after the stock lens. Know what i am saying?

Re: Osram PL520B 520nm Laser Diode

Thats interesting, thank you for sharing.

177mW @ 7V 435mA?

5mm or 9mm diode?.

Do you have a data sheet for it too?
