Is this a suitable spectrometer (although it seems dated) for gemology. I believe I read that the Holographic models were the better ones but could not find where I read it, so am unsure. Also looks to have a broader bandrange than most I have been looking at (very cheap).
I am trying to gather the correct parts to build a very cheap and basic spectrometer.
This would probably be a very good way to start out. StellarNet makes great spectrometers and this one can work with any computer with an Enhanced Parallel Port (EPP) StellarNet are very easy to get along with. Much more so than Ocean Optics.
You might want to contact them with the serial number of this unit. They will be able to tell you what its center wavelength and coverage are. The range mentioned in the auction probably is quoted from their web page referring to the line of instrurments and detector chips. It probably does not reflect this particular instrument.
I spoke with a StellarNet tech support this morning, and they said that they were not able to discern the settings of the unit by the serial number, but that the data on the tag would be correct for that unit.
After rereading the ebay listing the seller says the info came from the data tag, although that particular picture showing the data is too blurry for me to read. Seller states: Tag on the bottom reads as follows: StellarNet Inc. 813-855-8687 EPP2000C Spectrometer S#809101 UV 25ums Concave Holographic c1=.83993 c2=.000173 c3=189.0
Now can someone tell me what those numbers mean in english? I believe C1 is Max. wavelength C2 is slit size C3 is Min. wavelength I feel like I am in school when I visit this forum.
