Abstract
A dual resolution spectrometer includes a slit plate comprising a slit receiving light reflected from a measurement target. The slit plate directs the light reflected from the measurement target to a first mirror. The first mirror reflects light from the slit to a diffraction grating. The diffraction grating disperses light from the first mirror according to a wavelength of the light. The diffraction grating directs light in a first wavelength region to a second mirror and directs light in a second wavelength region to a third mirror. The second mirror reflects the light in the first wavelength region to a detector. The third mirror reflects the light in the second wavelength region to the detector. The detector detects the light in the first wavelength region and the light in the second wavelength region with different resolutions from each other.
