Dual-Field-of-View Multiband Optics

Multi-spectral-band systems are steadily emerging as a desired feature in a camera system. Each spectral band offers different image characteristics. Shorter-wavelength spectral bands provide the potential for better resolution due to the smaller impact of diffraction on the size of the optics blur. This means that a smaller-aperture optical system with a shorter wavelength can be used to see a further distance than that of a longer wavelength.
