ccd with response “time constant” of less than 0.5 ns & maximum “radiant sensitivity” exceeding 10 mA/W
Generally speaking, the specifications that export controls are concerned with are well outside the realm of typical consumer electronics. These are no exception.


  A response “time constant” of less than 0.5 ns


This describes an extremely fast CCD which can respond to light pulses in the GHz realm. The Sony CCD you've referenced has an integration time of 10 ms -- it's millions of times slower than what this specification is concerned with.


  “Specially designed” or modified to achieve 'charge multiplication' and having a maximum “radiant sensitivity” exceeding 10 mA/W;"


This describes an EMCCD -- an unusual type of high-efficiency CCD used in astronomy and various other applications, sometimes including biochemical research equipment (including Raman spectroscopy!). These CCDs require exotic cooling technology. However, the Sony ILX511 isn't one of these. It's a totally normal CCD designed for use in consumer electronics like bar code scanners -- its use in spectroscopes is incidental. It's fine.
