Plots compare bandpass properties of filters with prisms and gratings Efficiency characteristics of multi-spectral and Hyperspectral systems
Multispectral with Electronic filters Include: Liquid Crystal Tunable Filters (LCTF), Acousto Optic Tunable Filters (AOTF), and Interferometers (sequential wavelength by wavelength acquisition) Hyperspectral with Wavelength Dispersive Spectroscopy (WDS): All wavelengths acquired simultaneously. Based either on a prism, such as the PARISS system, or a diffraction grating
WDS Grating WDS Prism Filter (Multi-Spectral) Spectral Bandpass: High ~constant High (changes) Low (changes) Efficiency: Varies (medium to low) High (constant) Low (changes) High Order pollution: Significant None Significant (limits wavelength range) Wavelength acquisition: Simultaneous Simultaneous Sequential Field of View: Sequential Sequential Simultaneous Analytical data: Yes Yes No: relative

Spectral bandpass versus light throughput
Prism bandpass approximates an inverse relationship to camera QE therefore overall efficiency is greater than that of a grating.
