anybody have one of these modules? { 650nm 100mW }

[Data]

I purchased this off ebay:
AixiZ ebay store

I am thinking about putting it into a Longbow Micra 2310s body that I have yet to get. I suspect it will not fit entirely inside the head of the light but I may machine a protruding front for the light that integrates it together. Like how the SF L2 looks but with an even smaller front bezel diameter.

Should I drive it with one CR123 and if so how should I pump that up to the preferred 3.2 volts?

I would consider any other flashlight body too like one with two CR123s like the 5310s. I am not stuck on Longbow but I think they are nice quality for the money.


Cheers

It appears to be the same diameter and a little shorter than a Leadlight module. I put a Leadlight into a SF E2. It only required a bushing to hold the module and a slight mod to the head. If you do a search here for "Surefire laser", you should find it. I linked to my sketch of the mod and some pics.

Have you tried running the thing on 3 volts? I'd be interested to know how bright it is and if you can see the beam or not.

The bright degree of the 650 NMs is general to only have the bright degree of the 532 NM laser of 10/1 so the laser machine of the 650 NMs of the 100 MWs, a the 10 MW power that onlies have the 532 NMs is thus

iteresting. Does this module have APC or ACC? What are the beam quality and module quality like? Do you see power loss when unit warms up? thinking of getting one. Does the beam cut garbage bags if focused? thanks

That is a great looking mod. I had actually seen it when you posted it. It is very similar to what I want to do too. The only difference for mine is I do not want the laser to shine through any glass.

I agree with you about the laser in the rain. I did it too, please see my post with a picture: it is the 8th post from the top

It was raining heavy when I took this pic.

I agree it will not look as bright. However I love red lasers and they have no IR bounce. I love my greene but it has made my eyes uncomfortable feeling.

Hi Data,

Yeah, I've got one of those modules from that guy..

Well to be honest I'm a bit disappointed... /ubbthreads/images/graemlins/icon23.gif
The unit only puts out just under 85mW .
Needs a heatsink as it wanders around power-wise.
So I am sure it uses just Current control - It is very input voltage sensitive.
It would be way too easy to blow it up since it
does not regulate the input voltage...
It does NOT have blanking.

It is cheap , I dont recommend buying one.
There are much better units available /ubbthreads/images/graemlins/smile.gif

I do not know anymore about this module than was on the auction listing. With that said, I was not aware the 650nm diodes had the stability problems of the green laser systems. I thought that stability problem was caused by the crystals. Please educate me if I am wrong.

What unit would you suggest? I am open to anything.

85mW is close to what I was looking for. I will have to use a regulated power supply for it. Does its output power vary independent of input voltage?

 

[Guliver]

Yes, Its output varies quit a bit..

You might want to check out the link below , It might have some answers for you.

I just wanted to give you my experience without sounding too biased with that unit..
I didnt come here to try to sell you on anything ... see for yourself.

650nm have the same stability problems as any diode lasers and it's always a NICE adea to use APC circuit. As diode warms up, its efficiency drops like a rock and one need to crank current up a lot to compensate for the loss.

 

[Guliver]

Re: anybody have one of these modules? { 650nm 100

Yep
It would be nice to have an APC circuit in those, but the diodes used do not contain a photodiode.

Their are other ways to make them stable.

one way would be to at least have a regulator inside .
Another way would be a a zener (altho not the best solution).
that at least would give the circuit a reference to work against.. /ubbthreads/images/graemlins/blush.gif

My module came today. /ubbthreads/images/graemlins/party.gif /ubbthreads/images/graemlins/party.gif It says "660nm 100mw" on it so I guess he sent me the wrong one. I do not care much. It puts out a very pretty red. I just connected it to a single 123 cell that dropped to 2.8v when I applied the load. The voltage on the battery stayed constant for the 60 seconds or so I had it running. It did not get warm at all but I know it is not running full power either.

The lens focus in the front is real touchy and I will have to adjust it and put a drop of thread lock on the side of it to keep it in place.

They sent nothing with the module. I was hoping for a schematic on the circuit that is inside. I guess it is just a resister but I do not know for sure.

Can you see the beam clearly?

No, I can not see the beam at all. It is a cool dark night with 57% humidity. The laser is driven with only 2.9v and it is not focused well yet.

It projects a very powerful dark red dot about 2 ft. in diameter at about 300 ft. distance (my best guess).

I will report back when I get it driven at the 3.2v. My gaol is to do this with an up converter like a madmax but do not know how yet.

 

[bajaiman]

Thanks for the answer /ubbthreads/images/graemlins/smile.gif. I was thinking...would it be safe to run it with 3 x Nimh AA ... that'll be 3.6V ...

 

[Data]

I do not know. Somehow I doubt that the mfg of this module would tell me it is OK. I do not know its limits.

I think you should get one and try it out! /ubbthreads/images/graemlins/cool.gif
