1W 520nm NDG7475 Laser Diode In Copper Module W/X-Drive & Glass Lens

Description

Listing is for a single 1W 520nm
NDG7475
laser module. Copper diode mount for best thermal transfer and stability. It is prewired with a 2.2A Super X-Drive bucking laser driver and comes with a two element glass lens. The unit is ready to be dropped into your final project. No setting current or soldering diode to driver. Just mout the module in a heatsink and connect the leads to your power supply.
Input voltage range is 6V-9V. Great for use with two Li-Ion's. Suggest two 16340/18350/18650 3.7V Li-Ion's. You can also use a 6-9V 2A wall adapter or bench power supply.
Warning. I have had multiple customers informing me they have received 700mW NDG700 520 diodes from foreign sellers advertised as 1W 520 diodes or 1W 520nm NDG7475(T). Talked with my supplier who confirmed this is going on saying
it is a common practice currently. I also looked closely at some of the mentioned listings. The NDG700 700mW diode can be driven to 1W so they are selling them as 1W diodes. This may make it an accurate claim of potential power but confusing to customers. The actual NDG7475 1W 520nm diode can be driven to 1.4W easily with some of the more efficient ones doing 1.6W+ where the NDG700 can not exceed 1W and are less expensive. The one common thing I notices in all the of these listings was an edited version of the NDG7475 datasheet showing 1.8A as the drive current which is required for the NDG700 700mW diode to hit 1W. The datasheet for the NDG7574 is(and has always shown) 1.7A as the max drive current so if you see max drive current or forward current with 1.8A it is a pretty good bet they are NDG700 being offered.
Here is what you get. The X-Drive is encased in the back of the model connected to the diode.
Modules are wired with extremely flexible 26AWG wire that is burn proof and makes for very easy soldering.

Here is my testing on this diode
Nichia NDG7475 1W 520nm Laser Diode
Exciting day. Finally got my 1W Green diodes and could not wait to do some testing on them.:eg:
This 9mm diode has off center pins.
First thing I did is pop one in a sink and fire it up. Was amazed the brightness of the beam indoors during the day. Really bright.
Then beam specs and divergence seem to be nearly the exact same as the NDB7875 and M140 445nm diodes.
This diode with the G-2 has a pretty identical box reflection as the NDB7875 and M140 as well.
So next I decided to put the NDG7475 head to head with the NDB7875 @ 25 Feet they were both about 23mm with a G-2.
So now on to the meat here is the LPM test of the diode. I expected this thing to dim maybe around 2.5A but it just kept going. I decided to end it when I started getting foldback around 3.5A. There really was not much gain from 2.5A up but wanted to see where it dimmed but it never did at least to where I felt it would not blow up as they are kind of pricey.:whistle:
Would not suggest driving past this point. Stay 2.4A or under.
There you have it. Whole lot of of Green goodness. Oh and for some dark shots.
