Need help identify this laser module

[scooter1986]

Hi guys,im new here hope posting this in the right place.

Is any of you expert enough to figure out this "secret code" ? Would like to see a breakdown for this.

This is printed on a label: LR|SC|03|16120175
PCB number: 003-0039-00-A

What i know for sure, it has a 405nm, 250mW, housing 3.8mm diode in it and CW. no photo diode inside because only 2 legs are connected to the PCB
Thanks guys

They maybe just place and date of production, I think it's just a curiosity from you,seller didn't provide data, input?

i found this one online, the Data Legend looks similar code but not the same sadly.

Only the information i provided on my post known for this product.

photo wont tell much, but i will post some later

The BRD209 is a 3.8 mm diode in 405nm. I can't say that this is what you have, but they are fairly cheap and can be driven to 800 mW or even 900 mW if you get an efficient one. These are maximum powers so yours is set lower.

And, yes, a photo would help.

i just took some and upload them.

Yeah, I can't see anything here that makes the diode you have clearly one or another. It could still be a Pioneer BDR209 diode. That is the best I can come up with considering all your photos.

i see, is there any way to measure laser diode ? like i would get closer to identifying it, if i can determine the operational voltage and amps for example.

BDR-209 has a QR code on the back and it also has a small dot over it. will get a better pic when I get a moment. Also you said it was a 3.8mm diode? Hard to tell for sure but looking at the size of the window in relation to the body made me wonder.

Sure, we use CC/CV power supplies, laser power meters, spectrometers to measure the characteristics of laser diodes. But, this is not used to identify a diode. It is more to know the wavelength range, power output and the Vf and current needed to get these specifications out of a diode. It tells us the range of what to expect from a diode in question. Sometimes, there is no good way to absolutely identify a diode as being one part number or another.

Good to see you are getting help from our best minds.

HOWEVER-- no need to make a new post only 1 min after your last one--we are NOT FOND of double posting--you can edit and combine them please.
AND you have not completed your profile-- it needs at LEAST a general location like TEXAS'

BEFORE asking for help an introduction thread needs to be placed in the Welcome/newcomer section AS you are new correct??

My intro title was 'hello LPF from TEXAS'

we like to hear about you-- what are you wanting from lasers??
your school-job- other hobbies are good topics.
WITH LUCK (IF your title is good) you may hear from members near you..
we share a lot here-- use our meters to help others know the power .

If not already you will get help on how to power that diode-- my guess it will be a low power at first-- then push some and watch your LPM for the 'peak'==most here will protect the diode with lower power.

MYB send it to Paul- he has a super lab and will send it back no worrries,

buy eyewear BEFORE laser ALWAYS.

use our search before you ask Qs,

yeah, some of the diodes has QR code on the bot or side. mine only has on the label attached to the black and red wire.
this looks bigger housing then mine. i look at it under stereo microscope quiet a lot

is there any article i can follow to measure the (power output, Vf and current) ?

good advice, i cleaned it up and updated profile so as write on welcome page. thanks for you help to get started.
i keep in mind, but i rather not to send it out, its from my SLA printer and still using it until i find a new replacement for it.

Should be easier and less expensive to just buy a new diode module from the maker of the SLA printer.

The label on the wires is the part number of the module assemble not the diode, why not just order a new one if needed? Low power 405nm modules usually only run about $20-$40.

I was think about the same before, then i contacted them and they told me, i have to send the printer in for service because they not selling parts separate. They reasoning that this "isn't user replaceable part"
BTW Service fee 900euro + tax and it takes about 4 weeks. funny part is that in there service policy its saying the following

"Formlabs may use new, used, or reconditioned parts of equivalent or superior specifications in the repair of your machine. In some cases, and at its sole discretion, Formlabs may opt to replace a product with a new or refurbished product of equivalent or superior specifications. "

so basically after the service fee collected there is a chance i end up with a used module.
im pretty sure the diode itself not more then $100 worst case. As i checked online similar diodes around $20 or so.

closes i could find online for a ready module is this, but kind of risky specially when seller not even respond to my PM
also this order would take 30 business days with fastest shipping

this module compatible with form1 also, thats why has integrated PD inside of the diode.
form2 model not using PD. (you can see it on my pictures only 2 legs connected on PCB)
