WebGratings for Hyperspectral Imaging Our transmissive VPH gratings offer the optical designer many advantages. They are more efficient and much lower scatter than reflective ruled gratings. More robust to handling, they enable straight pass transmissive spectral instruments that are smaller in size, lower aberration, and easier to align. WebIn general, transmission grating based spectrometers (TGS) should be considered for spectroscopy applications and instruments where one or more of the following requirements are important: • Low light levels • Short integration time / fast spectral scans • Access to detector for OEM integration • High thermal stability
