    • A spectroscopic apparatus includes an optical system configured to transmit output light from a sample (1) irradiated with irradiation light from a light source (OS), a two-dimensional array light detector (2) configured to photograph light transmitted through the optical system, and a control unit (6). The optical system include a first optical device (3) disposed between the sample and the two-dimensional array light detector, a second optical device (4) disposed between the two-dimensional array light detector and the first optical device, and a variable band-pass filter (5, 7) 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.
    • 一种分光装置包括:光学系统,被配置为透射来自被来自光源(OS)的照射光照射的样品(1)的输出光;二维阵列光检测器(2),被配置为拍摄透过光学系统的光; 和控制单元(6)。 该光学系统包括设置在样品和二维阵列光检测器之间的第一光学装置(3),设置在二维阵列光检测器和第一光学装置之间的第二光学装置(4),以及可变带 (5,7),设置在第一光学装置和样本之间以及第二光学装置和二维阵列光检测器之间的至少一个空间中。 控制单元根据二维阵列光检测器的拍摄定时来改变可变带通滤波器的光透射波长带。
