PARISS: PMIS" imaging spectrometer-spectrophotometer model for quantitative spectral imaging
The PARISS imaging spectrometer-spectrophotometer records the spectra of objects imaged onto the entrance slit of the spectrometer. Spectra of objects in the field of view that pass through the slit are captured by a camera used as the spectral detector. A “C” mount adapter interfaces with the video port of a microscope or telescope.
The spectrometer acquires hundreds of spatially resolved spectra simultaneously, then custom software sorts the spectra into classes. (Details)
The imaging spectrometer-spectrophotometer works with all classical analytical spectroscopy methods over the spectral range from 365 to 920-nm. There is no need for order sorting filters for a spectral range of greater than an octave, because a prism refracts rather than diffracts.
If either the instrument moves across the FOV, such as in an aircraft, or the FOV is translated such as with a microscope, then the PARISS spectrometer-spectrophotometer can be used in hyperspectral imaging mode.
