Cool Doos! I notice that they list Adamas as one of their OEM applications. I wonder if the Raman and FTIR features are part of the Ocean Optics tool or if this is part of what Adamas adds. Have you ever seen one of these or know anyone who has one?

Hi Neil,

Yes one of the FGA alumni here demonstrated it a month ago orso, fits in the palm of your hand and plots nice printable charts.

Can you get outside the visual spectrum?
I would love to look at a scan of one of those reports if you can get it? Can you use this to determine HPHT and/or treatments in sapphire?

Neil

Neil,

It has a 200-1100nm range, so well outside the visible.
I'll ask if he has a digital scan for you/us and if treatment detections are possible.

The SAS-2000 is an awsome piece of equipment but it doesn't do what they say on CSI. I would love to have one.


I never said it did, I never even said the SAS-2000 was the machine. I saw a machine on CSI , thought it might have been a prop based on something real, and that is when I looked online and found the SAS-2000.

I was watching a CSI the other night where they were messing with diamonds and based on a report number etched on the girdle they were able to look up the owner and ownership history of the stone. Yeah right.

Neil


NOw that I could believe because I know more than one jeweler who sells etched ID stones, and they keep records of who they are sold to. Its more as a marketing / customer service thing, but I could see under the right circumstance, being able to trace ownership.

I am pretty friendly with Martin Haske who sells the SAS.

The biggest difference is how the spectrophotometer works in his machine and its related database.

Yes, the heart of his machine is a spectrophotometer, but you need to be a very advanced engineer and gemologist to put it together in a practical use so as to make it work.

Marty works very hard on improving the sofware and the database on an almost daily basis. Assembling the unit and preparing the database takes him 2-3 months to accomplish.

He and I are both night owls, so there are many times we chat at 2-4 in the am. Many times several times a day.

I wish the machine was less costly, as many of us do, but when compared to the Diamond Sure it is a lot less expensive, as the GIA Diamond Sure is about $ 60,000.

Also I am not sure that the Diamond Sure does as much as the SAS will do.

As for comparing the cost of it, if it saves you from buying a parcel of HPHT treated stones, or stones with radiation damage from treatment, it's worth it's weight in gold... maybe even Rhodium.

Geez Louise - I consider that PRICEY. Esp. since it's only 200-1100nm.

In my line of work, I had to purchase (ahem, my company purchased) a Perkin-Elmer 950 spectrophotometer that goes from 200nm to 3.3um (3300nm) in variable steps that can be as fine as 0.1nm (or less, not sure, never tried to push it there).

Double monochromater, uses 2 different light sources AND 2 different detectors (depending on the band you use).

And it was $54k. So not much more than the FULL up systems $45k.

Granted, I do totally different stuff.. but hey, output spectrum is output spectrum, right?

Great, now I'm wondering how to get a large enough slab of some gem to run through my spectrometer here at work...

Oh this site is going to be soooo badddd for me... :twisted:
