Abstract: An imaging apparatus includes a solid state imaging device having a light receiving characteristic in which an amount of light received reaches a maximum when an angle of incidence of parallel light, radiated at continuously changing angle, is not vertical (angle ? of incident light in the range of 3° to 15°) to a light receiving surface. This characteristic changes the amount of light received greatly when an aperture stop is opened, and enhances an opening/closing effect of the aperture stop. The solid state imaging device includes a core/clad light guide path structure, whose core serves as a light guide path. This light guide path includes a columnar portion located above a photodiode, and a lens portion on the columnar portion.

Abstract: A mass spectroscopy device constituted by a first reflector which is partially transparent and partially reflective, a transparent body, and a second reflector which is reflective. The first reflector and the second reflector are arranged on opposite sides of the transparent body so as to form an optical resonator in such a manner that when a specimen containing an analyte subject to mass spectroscopy is arranged in contact with a surface of the first reflector, and the surface is irradiated with measurement light, optical resonance occurs in the optical resonator, and intensifies an electric field on the surface, and the intensified electric field desorbs the analyte from the surface.
