Abstract
The present invention provides a spectral apparatus for spectrally separating light including a predetermined wavelength, including a slit that the light enters, a first optical system configured to collimate the light from the slit, a transmissive type diffraction element configured to diffract the light from the first optical system, and a second optical system including a first mirror configured to reflect the light diffracted by the transmissive type diffraction element, and a second mirror configured to reflect the light reflected by the first mirror and diffracted by the transmissive type diffraction element, and configured to make the light reciprocally travel between the first mirror and the second mirror via the transmissive type diffraction element.
