SPECTRAL DEVICE |
摘要 |
Provided is a spectral device which easily increases the variable range of a selected wavelength without an increase in the size of the device. A spectral device (1) comprises four band pass filters (11a to 11d) through which light (L2) from a light source (3) is selectively transmitted in a wavelength range in accordance with an incidence angle of the light (L2), and a flat rotary table (10) which has a main face (10a) on which the band pass filters (11a to 11d) stand and is configured to be rotatable around the rotary center (C1) along the main face (10a). The four band pass filters (11a to 11d) are disposed so that optical incidence faces (12) or optical exit faces (13) thereof are inclined relative to lines connecting the rotary center (C1) of the main face (10a) of the rotary table (10) and the center points (15a to 15d) of the band pass filters (11a to 11d) on the main face (10a), respectively. |
