I just acquired three spectrographs off Epay, and got them. I originally thought they had the 1x1024 or 1x256 EG&G sensors internally, but now am seeing that they have a much more sensitive system with cooling provisions, probably with TE cooling from the looks of them. I am not going to tear them up any further until I can research them further to see if I can get them working.
The have the following info on the Spectrograph body
Serv P/N 603461 Rev A
MFG P/N 604538
Instruments SA, Inc.
The EG&G sensor has the following
ABD MFG P/N 4306153 Rev A
Here is the original auction listing text:
It came out of a DNA Genome Mapping Machine, they used Air cooled Argon lasers and Hene lasers to cover a wide spectrum of the Human Gene ohm. It came with a bunch of Argon lasers we bought 5 years ago from the Silicon Valley Scrappers. I can’t use them they have a thermal chilled CCD in heavy gold plate housing. Also, there is a very fine line grating in the rear of the housing as seen in the picture of one that I took apart
Here are some photos:
The plate visible to the upper left is a block that goes between the optics and the image sensor module. The image sensor is probably bought out as a unit from EG&G and has nothing to do with the optics the vendor attached it to. The plate has a peep site that allows one to view the image sensor illuminated by the spectrum, which is pretty cool. It is a small hole covered with a plastic cover. The angular hole at the right side of the plate is the aperture which has a view of the image sensor. there is an eyepiece lens and mirror in this block of aluminum.
