Abstract
We present optical design of wideband spectrometer for space-borne telescopes for science observation. Multi-channel configuration is adopted to cover wide wavelength region from visible to mid-infrared. Basic design of each channels are consisting of mirror optics and reflective spectral disperser. Low, medium, and high dispersion spectrometers are studied. Influence of defocusing is analyzed. Each channels are combined based on use of dichroic mirrors.
