ABSTRACT:
The present invention discloses an apparatus for measuring spectrum and image with high spatial resolution and spectral resolution. The apparatus comprises an imaging side telecentric lens for collecting light from an object, an optical slit positioned behind the imaging side telecentric lens, an aspheric lens for collimating lights from the optical slits, a dispersing device for separating the lights of different wavelengths into a plurality of sub-rays of different entrance angle, an achromatic lens for focusing the sub-rays, and an optical sensor for detecting the optical intensity of the sub-rays. The dispersing device can be a transmission or reflection diffraction grating, and the optical sensor may consist of a plurality of photo-detectors positioned in a two dimensional array.
