CCD image sensor for modular spectrometer

Hi,

I would like to build a benchtop optical spectrometer based on this
image sensor or similar:

S7030/S7031 series back-thinned FFT-CCD made by Hamamatsu:

Any idea on how much one of these sensors costs? This one is pretty
high end I think.

I found an ebay auction with one of these image sensors hooked up to a
"detector head"

http://www.ebay.com/itm/Hamamatsu-High-sensitivity-Detector-Head-Model-C7041-/390300949910

Here is the datasheet for the detector head:

http://www.rocketresearch.org/new/spectrometer/c7040_c7041_kacc1034e14.pdf

My plan is to mount the CCD to a custom PCB that implements the detector
head functionality and has a USB interface to send the CCD data to PC.
Then use a fixed optical grating to shine light onto the CCD (like most
common spectrometers seem to do). I would like it to be capable of
doing Raman spectroscopy as well as "normal" spectroscopy.

Any advice for making this spectrometer? If anyone else is interested
in this project let me know.

cheers,
Jamie
 
Look for 1D cameras such as 4096x1, which are used in film scanning or
scanning objects on the assembly line.

That products appears to be able to resolve only 100 spectral lines.

If a 2D element is used, you could build a imaging spectrometer in
which the Y-axis represents the various wavelengths, the X-axis
represents actual pixels in the X-axis line, you have a multispectral
1D camera.

With mechanical tilting of the grating an CCD in up-down direction,
you can construct a imaging 2D multispectral camera.
