I need to go over which diodes go into what kind of module and the various currents each need to be set to. It will make tomorrow a very busy day for me.
you're welcome I want to collect every wavelength in his pocket series, I always seem to have more expenses everytime I turn around so itll take a long time for me lol!Awesome... Well, now I want some lasers from Sanwu... Will think about it. Thanks for sharing.
:thanks: for this info Cy. how did you get these results? I only ask because Id really like to do these tests with mine.I don't feel like making a new thread so I'm just throwing my results in here instead:
Paid April 02, shipped April 16, arrived April 30
Measured power: 63mW
input current draw: 200mA at 5V input; 280mA at 3.6V input; 1.2A at 1.6V. It is not in regulation below 1.6V
The label says 489nm, and I verified it indeed measured 489nm.
haha yeah sorry that sounded like a noob question. the way you worded it made it sound more complex, I guess in a way i already knew the answer i just wanted to make sure i don't do anything wrong when I test it.Are you asking how to measure power, voltage, current and wavelength? Power meter, voltmeter, ammeter, and spectrometer respectively. The power meter is a Gentec TPM310, the volt/ammeter are integrated into a lab power supply which is a Tenma 72-6908, and the spectrometer is a science-surplus device.
Hey, Josh. Your package was picked up today and tracking has it headed for Seattle. I always track any packages I send out to make sure they get to their destination. :yh:
yeah that would have been pretty cool. well next time you come to Oklahoma youll know what street ill be onNice Sanwu Pocket, Richie!! That color looks great!!
I wish we coulda met up when I was in town... Perhaps next time buddy
thanks a lot AlexI really like the pictures showing off the two wavelengths, stunning! Nice job Richie! :beer:
you will definitely have to show it off :beer:Can’t wait, Paul. I think I’m gonna put that set-up into a chromed pen host I have. Nothing original but she’ll be purdy.
Thank you, sir!!
I saw this in another thread. Just out of curiosity, which spectrometer do you have? I have an Ocean Optics USB2000+. I also have three B&W TEK spectrometers which I removed from some medical laser equipment. They don't seem to be as accurate or as precise as my Ocean Optics, though. I believe they are the same spectrometers used in the Science Surplus units, but those have the gratings changed out in them.488nm is my new favourite wavelength; just yesterday I received a 488nm portable directly-injected diode laser from overseas; I knew from the time that I fired it up that it would spectro somewhere very close to 488nm, and when I did spectro it, I got a wavelength of 488.7nm!
Needless to say I'm extremely happy with it!!! :wave:
