PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please sub

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

I just ordered a boost driver from Techhood. It provides a Vf~5.5 VDC and has a pot for adjustment. Soft start and reverse protection all for $5.00 with free shipping. I'm going to do some testing to see if it is capable of driving some of these Sharp diodes we've being getting.

Important info on 473nm unit spectro.

Just popped the lid off mine and there are no baffles inside it. Just the slit on the fiber input, optics and ccd sensor.

Huh, interesting. That may make life easier for all of us. Thanks for the update! :beer:

That's a bit confusing, as it isn't what I was told by a seller who has a half dozen or more of these. I wonder if there is something in the CCD setup that limits its range. I'll know more once i get into it. BTW, if you touch any part of the optics you can ruin them from the oils on your hand. This is especially true of the grating. Be very careful when you have the cover off the optical bench.

OK I've emailed the ebay seller asking to have five sent to you and five sent to my home address in Alaska.

Edit: Hey, anyone know what use these were designed for?

Translated from the following page:Was a link to some Some Czech auction site until they killed the link.
Searching for "BPS473" is what yielded this result.

"The Biophotonic Scanner is the world's first measuring device that determines the Carotenoid Value in the Skin (SCS) - an instant recording of carotenoid antioxidant activity in your body. By simply placing your hand in front of the faint blue light, you can get your Carotenoid Value in your skin within minutes. The Pharmanex® Biophotonic Scanner Technology is based on an optical method known as Raman Resonance Spectroscopy. This technology has been awarded the Nobel Prize and is used for biological measurements, as well as scientific discipline supported by years of research. Thanks to Pharmanex, technology is now available to everyone. The scanner uses optical signals to measure carotenoid levels in human tissue just below the skin's surface. These signals identify the specific molecular structure of carotenoids. Pharmanex® is the exclusive holder of the patented Biophotonic Scanner technology. The scanner was developed by physicians and physicists at the top university in the United States"


EDIT: Knowing it's original purpose, it does not surprise me that there are no baffles in the spectrometer on these. Will not at all be surprised to be able to hook it up and use it as is just as soon as I find either my arduino or my usb to 9 pin serial converter. Just have to hope it has a decent range that it can read.

After looking at the optical bench, I was able to identify the collimating mirror, diffraction grating, focusing mirror and CCD. Can't say that it's configured to read all of the VIS spectrum, but it does have everything necessary to do so.

If you can post photo's showing things better inside I would sure like to see, but I should be getting mine in the mail in a week, so not needed. The seller responded to my email requesting to send 5 of them to your address, he agreed.

Thanks, Alaskan. I got your PM. I was going off CynicalBrad's photo in post #3651. I haven't yet got the optical bench out of the one on my bench. Too many things going on. It takes me time to get it apart.

Collimating mirror is the smaller concave mirror, grating is the flat optic and focusing mirror is the wider concave mirror I take it?

Edit, for reference in case anyone needs it:

Paul, I just found a link in this thread to more photo's: https://www.photonlexicon.com/forums/showthread.php/11161-BWB-10-OEM-473nm-laser-module-info-thread - I found what I wanted there and more! No need now, tks anyway.

I posted that link earlier in the thread. :p Don't recall seeing anything about the spectrometer in there though, just the laser head and driver.

You got the optical parts identified correctly, diachi. That is how the bench is setup.

Cool! :)

Now let's just hope the range is good enough on these. :D
 
Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

Yep, there weren't any photo's of the spectrometer in there, although that is of interest to me too. I really wanted to see that DPSS module the most right now, I didn't want to ask Paul to open it up, he's already volunteering enough of his time, but truth be known, that was what I wanted to see the most right now.

Although I am hopeful the spectrometer can be used in a range useful to us for VIS, even better if it can go longer, but I'm not too hopeful for even the full vis range right now. I've been wanting a spectrometer for a couple of years, so perhaps my peaked interest in the DPSS portion shouldn't be on the top of my mind.

I'm glad these are the ones with the pump correction optics and not the other ones with just the pump focusing lens, like the last one I had.

Lots of space for a DPSS build or just a pure diode build.

IIRC, they don't have the output collimation optics on them as shown above. Not sure about pump correction optics, definitely at least two "focusing" lenses and an anamorphic prism pair though.
