IMAGING APPARATUS AND ANALYZER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an imaging apparatus capable of spectroscopic-imaging with narrow wavelength band and wide field angle.SOLUTION: The imaging apparatus includes: an optical system L which has lenses L1 and L3 and a diaphragm S; an imaging element N which has first and second pixels into which a beam of light passing through the optical system L enters; and an optical element array K disposed between the optical system L and the imaging element N. The optical system L has an optical filter L2 which includes a first area and a second area the optical characteristics of which are different from each other. The optical element array K projects the light beam passing through the first area onto the first pixel; and the light beam passing through the second area onto the second pixel. An entrance pupil E of the optical system L is positioned between the diaphragm S and a subject.
