Mini-review 50mW Green module from Fasttech

Nice work offroad that came out amazing!!!!

Just got mine in it measure 115mw thanks for posting this review!

Made some pictures gotta love green:

I love the nice dot and thin beam of this one

These modules are easy to put in penlasers or standard 12mm heatsinks.
100mW green is very bright. We don't need multiwatt lasers for brightness.

That is amazing. :drool:

The part I like the most Is that I measured it with an IR pass filter and only got 6mw ! I will retest again tonight though to confirm.

I went ahead and got 3 of these. I needed a good laser for my side arm right?
(attached if your interested, not near finished)

I had a question though. On the over spec modueles, are people adjusting them up to a higher level witch they deem stable, or are they just arriving that way from factory?

I got my order of 5 today and here is what I found out with them.

...start up...30 seconds later...after pot mod.
1...89...............75.....................80mW
2...59...............60.....................91mW
3...75...............83.....................59mW :cryyy:
4...69...............92.....................110mW
5...63...............83.....................90mW

The pot was adjusted to increase the current draw by an average of 60 ma.
Nothing I did could bring No#3 above 59mW after the current was turned up once. all readings are mili watts.

I got my laser built and now I just need to find an LPM for all three of my unmetered lasers lol.

@ pyro: well that answered my question perfectly, nice little chart you made there

Thanks for the testing. 59mW is still overspec.

I just got mine earlier today and am very pleased. No DOA and all are noticeably brighter than my tested 50mw greeny. I'll try and egg out a rough estimate later based on some temp readings i got off my thermocouple... but those will just be ballpark. The best one read over 30F higher than my 50mw though, so I know for sure it's overspec
(lowest read 19F higher)

I only use Fahrenheit due to the better resolution on my thermocouple, FYI.

I was wondering though, is there some sort of cheap cap that will screw onto the end of these modules? or is that a custom job?

 

[bdgreenb]

custom job, used a sanded aixiz module head backwards and sanded the threads on the green, looks pretty sweet.
I fit mine in a E3 which has the screw on cap to hide WL incompetence (Luckily it hid mine as well :crackup: )
Has anyone received any of these underspec? All 5 i've ordered so far seem to out-do each other.

 

[Blord]

The 50mW green module from Fasttech have a good overspec ratio. Almost every module is outputting significantly higher than 50mW.
I haven't heard much about underspec or dead modules. Hopefully Fasttech has a large stock of these green modules. A new batch could be worse.

Alright, I finished my build first build with this module (of the 3 I have)
The optics spread the beam to about 1/2'' (12mm) over a distance of about 30 feet, down my hallway.

It popped some black balloons at close range though, scared me a bit, wasnt expecting it :scared:

Well here are a few pics, no smoke or anything, just my room. I'm really liking these
The build was in the shell of an overspec 5mw ebay pen... that I broke
some JB weld and a little sharpie to make the front nice.

Beam shots on my garbage camera, in the light, attached below.

So what component would one heat sink on the driver to avoid over heating?

Also I made this. (I was really tired when I made the video)


All I did was short the switch, solder a spring on the negative contact point, desolder the positive, and add a spring with two solder blobs to bridge the gap for the positive.

I probably could have been easier but I got it working

 

[Blord]

Usually it is the large IC in the driver but this case it would be better to heatsink the brass module. Green DPSS laser are very susceptible on temperature.
