The CCD is a Sony ILX551. They are sold as a vintage electronic components. The concave diffraction grating is focused on the CCD and it comes from a discarted Agilent spectrometer, thus, I don't have the details (perhaps 300 lines/mm). In the former apparatus it was used in the UV and visible range with a resolution around 1 nm. The yellow doublet of mercury is resolved but the doublet of sodium don't. I use it in the 1st order spectrum. The second order is too dim.
A lot of older flatbed scanners use linear CCDs.

Also, can you give any deatils about the grating?
Groove density, dimensions, blaze wavelength?
Thanks again.

Nice video. I wish you had narrated the detail of construction, but pretty cool.
What linear ccd did you use and how did you get it? They seem to be hard to find.
