Review - DX 200mW Green Modules - Laser Pointer Forums

billg519 · 10-31-2009, 10:45 PM

I ordered two of these modules from DX on August 1st. They did not ship these until October 15th, and I received them October 26th. Despite nearly no padding around them in the brown envelope they came in, both arrived in perfect working order. As I recently purchased a Laserbee LPM, I used it to measure the performance of these modules.

The first module output 75mW to start and gradually rose in power as the module warmed up. Output settled at 142mW, taking 90 seconds to get there. Leaving the module on a little longer let it fluctuate between 138 and 145mW.

The second module output rose steadily and rapidly over 30 seconds, reaching a peak of 146mW and settling back to 122mW.

First photo shows the module unscrewed in half showing the crystal mount.

Next two photos show top and bottom of module.

The last photo shows a module, a module in a brass host (1 x 10440), and a DX dilda for size comparison.

I wasn't expecting to get a full 200mW of power for the price of these modules. I am surprised that they exceed 100mw. They are a little better than I was expecting. To put one in a host, the black wire can be unsoldered and replaced by a spring, negative of battery goes to this spring. The red wire is not needed and can be unsoldered or cut off. The brass is the positive connection. A trace on the board goes from the red wire to the case lead of the diode. Positive of battery would touch the tailcap. As long as the brass body makes good electrical contact with the host everything will work. In the host above, the module is a gentle press fit into the host. Good contact and good heat transfer. For anyone still interested in these, beware of the slow processing of DX ...

Nice deal for the price.
How is beam divergence, is their allot of scatter?

Hemlock_Mike · 10-31-2009, 11:41 PM

That's about what I got but in mine, everything had come apart. I had to reallign the POS.

One of them had some crap on the lens, but once I cleaned it the beam cleaned right up. Neither unit exhibited any sign of mode-hopping. The beam exits at 1.5mm diameter and measures 15mm at 45 feet.

I'm gonna add this to the RT as neutral since many other members that got this module got screwed over the diode dying prematurely.

megha · 12-16-2009, 03:05 AM

which battery do you think that is appropiate for this module ? or how much voltage ?
6V is ok?

jaws2002 · 12-16-2009, 03:19 AM

NOOOO 6v. 3.6v at the most. Probably safest with a 3v.

megha · 12-16-2009, 03:55 AM

thanks for the soon answers

would this module fit in the normal cheap 5mW laser pointers? :
Newest 5mW 5 mW 532nm Green Beam Laser Pointer Pen - eBay (item 170420053178 end time Jan-12-10 22:53:44 PST)

and is this DX 200mW module is the same that these one uses? :

DealExtreme: $59.99 200mW Green Laser Pointer Pen Black

maybe the use the same or maybe they put a worse one in the pointer ?

Thanks again,
Ramiro

Wow totaly awsome review... basically, I get 130 mW green module for 45$! Nice! O-like has a 100 mW module for 60 $... Well they do have the quality but... I ain't got money, I might considder getting one of these after Christmass, when I will most likely end up with some $$$.
What is the chance I get a defective one? Both of those seem OK, but considering my luck, I'd most likely end up with one working out of 10 ordered.

That`s so good ! 130mW green for $45.00. Good deal. I`ve also bought that module, they have shipped it yesterday, so I`ll have it in about 3 weeks because of chiristmas and new year.

How much voltage are you using ? or which battery / supply ?
Did you put the module into a host ?
Could you show some beam pictures at night in outside (exterior) ?

Thanks, that would help me !

realista · 12-16-2009, 09:04 PM

.... i think that the 100 and 200mw version of this module.. is the same module... or not???

and i think that the olike 200mw module.. is quite the same module....

I don`t think that they are the same. DX will never sell you something spected at 100mW that will give 130mW. The worse "200mW" that I`ve heard are about 80mW and if you are lucky you`ll have 80mW from a "100mW" module. It`s just my opinion from what I`ve read, not really tested by me.

Umm... you asking me that or billg519?
I have no green modules mentioned

Sorry, I missunderstood when you`ve said "I get". I tought you where really getting that. Not supposed to. Sorry

Don't worry about it, ask Bill, he knows everything you need to know!

realista · 12-17-2009, 06:15 PM

@megha...... i think dealextreme does not test his module..... he only order for example 3 quality of moduled.... one for range 5...30.... one for 30...100... one for 200. but... when the seller ship to dx a 200mw module.. it could be 80... 10.. max 130...(only optotronics and other good seller have LITTLE module ..over true 140mw...), but i think you can expect from a 100mw module.. also 100mw... or 120mw. the200mw is only NOMINAL POWER.... it is about 100mw.. sometimes above.. sometimes below... but the 100 mw is more trustable to be about 80... or 100.

maybe i am wrong... i don't know! mut this is my 6 sense....PS...can you test the power with ir filter?you got about 140mw...(good luck

) but true green could be 100/110mw... ah... can you say me if the mrad of the beam is good?.. (i say good when it is lower than 1.5mrad....and perfect when it is about 1 mrad)

Eudaimonium · 12-17-2009, 07:23 PM

Alrighty, I managed to do some business and if it turns out Ok, I'll be selling my 50 mW green laser, and I'll use the money to buy 200 mW DX green laser module. So I'll see if the module is somewhat up to specs. If it outputs about 130 mW as stated by Bill, it should be able to ignite matches, which is more than good enough for me.

I will let all you know how it turns out one I got it, however don't hold your breath till then, It'll most likely be in the early days of next year.

BTW @Bill, I'm hopin' to have my LPM finished by then, so I can put it to good use,
and also, did you measure that powers with or w/o IR filter? And can it really ingnite matches? I hope so!

billg519 · 12-18-2009, 01:09 AM

I grabbed a module and let it warm up. It was outputting 141mW on my Laserbee. I then put an IR filter plate in front of the LPM. The reading dropped to 96mW, (probably losing up to 6% of the 532 in the filter) so there is a significant IR component to the output. Using a video camera, I shone the laser through safety goggles, so that I could view the IR output. This output was surprisingly well collimated, the IR spot was the size of a penny at ten feet. Putting the laser goggles between the laser and the LPM let me measure the IR at 24mW, the goggles block some of it. Yes, with a focusing lens, I lit a red wooden match. The IR probably helps ...

Brass laser shown uses 1 x 10440.

Aww crap... so basically that is 100 mW module, for 45$... still comes of cheaper than O-like, but considering quality of product (and possibility of getting defective one is slightly highen on DX)... I dunno...
I must give it a thought or two, but for now I'm undecided.
Bill, what do you suggest?

After a ton of reddies and couple of blurays... I really must get myself a new green laser, more powerfull. But if it ain't worth it, I'll just get myself some more PHR sleds

What power supply are you using ? I mean, which batteries or voltages ? I`ve read that 3.0V may be ok, and never go more than 3.7V. Is that correct for you?

Thanks !

Lew8 · 01-25-2010, 03:53 AM

do these modules use 9mm 808nm pumps? if so could you take the driver off and use a more precise one to push up the output to real 200mw? or would the crystal crack in a pointer setup? any idea what the power of the pump is in this module? 1000mw? if not could u put a known 1000mw pump in? thanks

The problem is not the diode, cheap green pointers all use the same or similar crystals made for about 50mW green. In the "200mW" pointers they put a more powerful pump diode in there, but the crystal is the same, so the crystal is overdriven and outputs less and is less stable.

Lew8 · 01-25-2010, 08:46 AM

thanks for the reply

v helpfull.
would it damage the crystal in these modules if you pumped them high enough to produce 200mw? is it just a matter of heat dissipation from the crystal?
do you or anyone else know what the actual power of the pump diodes in these are?
Does anyone have any dimensions for these other than 60x12dia so that i can add them to my sketchup 3d laser parts library plz?

Thanks

This kind of contradicts this post:
