Abstract: A hard-apertureless spectrometer includes a housing, a collimator configured to collimate light provided from a soft-aperture of a target, a diffraction grating configured to spectroscopically analyze the collimated light, a condenser configured to condense the spectroscopically analyzed light, and a photodetector configured to receive the condensed light output from the condenser and detect a target characteristic.

Abstract: A spectrometer that includes: a first diffraction grating configured to spectroscopically process provided light; a first detection unit configured to condense light spectroscopically processed by the first diffraction grating and to output an electrical signal corresponding to condensed light; a second diffraction grating configured to spectroscopically process 0th order light provided by the first diffraction grating; and a second detection unit configured to condense light spectroscopically processed by the second diffraction grating and to output an electrical signal corresponding to condensed light.
