Patent ID: 7869036

Claim:
An analysis apparatus for analyzing a specimen, comprising: a spectral separator for dispersing spatially an electromagnetic wave from the specimen into spectral components; a sensing element array containing plural sensing elements for sensing the spectral components of the electromagnetic wave dispersed spatially by the spectral separator; and a spectrum calculator for calculating a spectrum based on a signal from the sensing elements; wherein the spectral separator and the sensing element array are placed so that the incident angles of the spectral components dispersed spatially by the spectral separator to the sensor elements are different for each of the sensing elements, wherein the sensing element has an electromagnetic wave sensor and a filter for selecting the wavelength range for sensing the electromagnetic wave introduced from the specimen, wherein the filter comprises a negative dielectric medium having a negative real part and a second medium, wherein the negative dielectric medium and the second medium are placed at a distance of not more than the wavelength of the electromagnetic wave to be sensed, and wherein the filter and the electromagnetic wave sensor are placed at a distance of not more than the wavelength of the electromagnetic wave to be sensed.
