Abstract

An optical apparatus for capturing spectral images includes a variable spectroscopy device having first and second optical members that face each other and have a space therebetween, the spectral characteristics of the variable spectroscopy device being changed in accordance with changes in the relative positions of these optical members; a frame member that fixes the first optical member in place; a driving section disposed between the frame member and the second optical member, and transferring the second optical member with respect to the frame member in accordance with driving signals input to the driving section; and an optical element that deflects or disperses light beams passing through the variable spectroscopy device or a photoelectric conversion element that conducts photoelectric conversion. The optical element or the photoelectric conversion element is supported by the frame member.
