The optic system inside the Nano-Hyperspectral sensor based on offner spectrometer: the light passing through the slit is projected in the focal plane (camera array of CCD) with almost no distortions. Next, the light is separated according to the wavelength creating a hyper pixel. Adapted from Headwall Photonics, Inc.
