Abstract
A spectroscopic apparatus includes an optical system configured to transmit output light from a sample irradiated with irradiation light from a light source, a two-dimensional array light detector configured to photograph light transmitted through the optical system, and a control unit. The optical system includes a first optical device disposed between the sample and the two-dimensional array light detector, a second optical device disposed between the two-dimensional array light detector and the first optical device, and a variable band-pass filter disposed in at least one of spaces between the first optical device and the sample and between the second optical device and the two-dimensional array light detector. The control unit changes a light transmission wavelength band of the variable band-pass filter in accordance with a photographing timing of the two-dimensional array light detector.
