The Next Generation Sky Survey Telescope is a spaceborne cryogenic optical telescope with four channels covering the wavelength range 3.5 to 23 microns. The 0.5 m aperture telescope is based on a modified three mirror afocal design, with a scan mirror at the exit pupil compensating for the spacecraft motion. After the scan mirror, the light is spectrally split and focused by three refractive camera systems onto four detector arrays. The nominal optical design exceeds the requirement of diffraction limited performance at 8 microns wavelength over the 1 degree by 0.5 degree field of regard.
