Spectroscopy device, spectroscopy apparatus and spectroscopy method

A spectroscopy device that separates input light into a plurality of wavelength ranges includes a metal body (10) with a hole or aperture (20; 21) which is open on the upper side. The hole or aperture (20; 21) is formed in a polygonal shape having at least a pair of opposite faces (11,12; 1103) not...

Zusammenfassung:A spectroscopy device that separates input light into a plurality of wavelength ranges includes a metal body (10) with a hole or aperture (20; 21) which is open on the upper side. The hole or aperture (20; 21) is formed in a polygonal shape having at least a pair of opposite faces (11,12; 1103) not parallel to each other in horizontal cross-section, and inner side faces of the hole or aperture are finished as mirror-reflective surfaces (11,12; 1103). Polarized input light inputted from the opening to the hole or aperture is reflected by the reflection surfaces (11,12; 1103) and a standing wave is generated inside of the hole or aperture (20; 21) by self interference, whereby the input light is separated into a plurality of wavelength ranges.
