I also have the filter and laser part, but the performance of the filter and beam splitter probe is too poor for it to be useful.

At least mine have strong self-fluorescence, making it hard to get a meaningful data as the laser intensity are not that stable. Also the short excitation wavelength of 423 nm led to significant fluorescence in many samples I tried.

Reading out those CCDs needs some signal conditioning and ADC, the time needed to build and debug them by myself worth more than a second hand Ocean Optics or Verity, so I wouldn't bother.
