PARISS imaging spectrometer 
PARISS imaging spectrograph: Weight: 1,250 g (Excluding a camera) Moving parts: None, Optimizes stability and reproducibility Aberration Correction: The wavelength dispersive element is a prism with optical “power.” Concave and convex surfaces on the front and rear surfaces correct astigmatism, coma, and spherical aberration. Spectral range: 365 to ~920 nm or 400 to ~990 nm, depending on choice of camera. All spectra acquired simultaneously without order sorting filters Light throughput efficiency: Internal transmission ~90% from 450 to ~920 nm. Entrance slit dimensions: Standard 5 mm. by 25 micron, widths of 50 and 100 micron are available in pre-aligned mounting assemblies. Spatial resolution at the sample: Depends on slit width and camera pixel size ~ 0.6 micron by ~0.6 micron with 40x magnification typical.  Nanoparticles may be detected but not resolved Spectral resolution: ~1 nm measured at the full width at half maximum of the 436 nm Hg line, depends on slit width and camera pixel size.
The PARISS spectrograph is made in the USA
Non-imaging spectrometers take a point on the entrance slit and presents it as a line at the detector (due to astigmatism) at each wavelength. A linear array is a suitable detector.
Imaging spectrometers take a point on the entrance slit and presents it as a point on the focal plane at each wavelength.  A CCD camera will observe the spectra of points on the entrance slit along rows of pixels.
The PARISS curved prism, integrates the properties of a lens enabling state-of-the- art spectral and spatial imaging.
