Hello - is anyone aware of a spectrophotometer that is capable of
taking measurements with the speed of 2-3 KHz?

Thanks

No. As a reference the Eye-One Pro Rev. D samples at about 210Hz max.
Something like an Ocean Optics USB4000 boasts a minimum 3.8 milliseconds
integration time that translates to 260 Hz. Perhaps there are faster
systems if you go looking.

The minimum integration time is stored in the EEProm on the i1.
Gretag/X-Rite make an SDK available for their instruments, which
is the usual way application would access them. Since this SDK
doesn't run on Linux, I deciphered the USB interface for my particular
purposes.
