| 1. An optical apparatus for capturing spectral images, comprising:
a variable spectroscopy device having a first optical member and a second optical member that face each other and have a space
therebetween, wherein the spectral characteristics of the variable spectroscopy device are 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, wherein
the optical element or the photoelectric conversion element is supported by the frame member.
