What could this be?
Union Biometrica Copas Laser Harvard Bioscience Laboratory System Curtis 308 HRS | eBay

I think it may have an argon inside but I am not sure. Is it worth the risk to buy it?

It does, I can see the PSU through one of the grating on the side. May have fiber out?

In one picture the fiber looks like broken.

Sure does - although it can be removed. Fiber coupler screws onto the front of the head. IIRC they usually have an SMA fiber connector on them, so you could replace the fiber in that case, if you wanted to use it.

The laser is in unknown condition though. :/

AR Mechanical Mod 18650 Mod 510 Thread Steel FAST FREE SHIPPING | eBay - Does anyone know what material this might be? It claims both SS and brass, and I'm not sure which to believe.

The second, third, and fourth pics, seem to show a stainless & brass combo mod, the first pic looks like a copper unit. The mod actally looks to be chrome plated, and not S.S.
It looks as if the seller is only offering the steel model.

Here is another offering of that seller showing the steel mod in his pics.

I just purchased over 50+ diodes 670nm and 638nm all 9mm and a lot of optics' in a box for $30 bidding
he also told me tare are some other diodes all new packed 690nm and some other i was looking on the diodes package and i saw writing on it 652 no idea if its nm could not read it since its covered by other static diode package :thinking:

NICHIA NUBM06 445nm 4W Hi-Power BLUE DIODE extracted from array with ball lens | eBay

If these NUBM06 diodes that Techhood is selling have the good ball lens or even the 2nd best ball lens then I could knife edge them into a large double concave followed by a sliding PCX.
I think if I used articulated mounts made from 1/2 inch aluminum stock I could use every other mirror or at least #1, #4, #7 of the old 5.6mm diode, 8 mirror KE arrays and do it all on the cheap.

I would really like to find some 5X or 7X BE's with 50 - 75mm output lenses, and 10 - 12mm inputs, but if not just plain scientific lenses would work and they are not expensive, I think there's like 5% reflective loss.

If these get down to 20 dollars a piece I am going to have to have some fun with them.

Anyone know what model this might be? Probably Coherent Avia UV laser, no idea what power.

I just got a look at the inside and all I can say is WOW ! As a huge fan of anything PRECISION AND ULTRA HIGH QUALITY I know it when I see it and I just seen it !

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

Very interesting. I see an oven with a beam mask and a lot of built in adjustment, possibly something is missing?

 

[Alaskan]

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

I don't know if the holes are something missing, or some option which wasn't ordered. I believe this unit had an external 808nm IR input, then vanadate converted to 1064nm, then to a VIS wavelength and last to UV. Trying to figure out what it has in it. Been googling Coherent Avia and finding some, but no pictures of the inside of what ever unit this is.

The holes will be for adjustments or the option of additional/different components. Allows some customization without much hassle.

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

I understand all the rows of adjustment holes, I was looking at this.
