Abstract: The invention relates to an optical filter and a method for its production, and to a device for the examination of the spectral and spatial distribution of an electromagnetic radiation irradiated from an object. The invention is based on the task of providing an optical filter of the above described type that is inexpensive to produce, which can be used to detect a plurality of wavelengths, in which, however, tuning of the DBR mirrors by means of displacement is not necessary. Furthermore, a method for the production of such a filter is provided. According to a first aspect of the present invention this task is solved by a method for the production of an optical filter array having two DBR mirrors, and a cavity present between the same, comprising cavity sections having a plurality of different heights, each forming one Fabry Perot filter element, characterized by the following steps: applying a first DBR mirror onto a substrate, forming of a layer comprised of a cavity material on the DBR mirror, wherein this layer is equipped with a plurality of cavity sections forming the filter elements by means of utilizing a nanoimprint method, and applying the second DBR mirror on the cavity material having a structuring that is defined by the different heights of the cavity sections.

Abstract: A spectral image acquiring apparatus includes an optical filter on which light is incident; an image sensor including a two-dimensionally disposed pixel array for detecting the light via the optical filter; and a signal processing unit generating a difference-value image based on a detection signal from the image sensor. The optical filter includes a diffraction grating having a lattice pattern corresponding to one or more pixels on the image sensor. The signal processing unit calculates a difference value in an amount of received light between two adjacent pixels based on the detection signal from the image sensor, and generates the difference-value image based on the difference value. The difference value between the two adjacent pixels is varied depending on a difference in an interference point on the image sensor corresponding to a diffraction angle of the light that has passed through the diffraction grating.

Abstract: Calibration of an arbitrary spectrometer can use a stable monolithic interferometer as a wavelength calibration standard. Light from a polychromatic light source is input to the monolithic interferometer where it undergoes interference based on the optical path difference (OPD) of the interferometer. The resulting wavelength-modulated output beam is analyzed by a reference spectrometer to generate reference data. The output beam from the interferometer can be provided to an arbitrary spectral instrument. Wavelength calibration of the arbitrary spectral instrument may then be performed based on a comparison of the spectral instrument output with the reference data. By appropriate choice of materials for the monolithic interferometer, a highly stable structure can be fabricated that has a wide field and/or is thermally compensated. Because the interferometer is stable, the one-time generated reference data can be used over an extended period of time without re-characterization.

Abstract: A spectroscopic module 1 is provided with a spectroscopic unit 8 and a photodetector 9 in addition to a spectroscopic unit 4 and a photodetector 5 and thus can enhance its detection sensitivity for light in a wide wavelength range or different wavelength regions of light. A light-transmitting hole 5b and a light-absorbing layer 12 are disposed between light detecting portions 5a, 9a, while a reflection unit 7 is provided so as to oppose the layer 12 (i.e., region R), whereby the size can be kept from becoming larger. Ambient light La is absorbed by the layer 12. Any part of the light La transmitted through the region R in the layer 12 is reflected to the region R by the unit 7 formed so as to oppose the region R, whereby stray light can be inhibited from being caused by the incidence of the light La.

Abstract: The present invention discloses a multi-cavity optical sensing and thermopile infrared sensing system, which comprises an optical sensing part, a dielectric layer, a plurality of optical cavities, and a plurality of thermocouples. The dielectric layer covers on the top of the optical sensing part. The optical cavities are formed by a plurality of metal reflectors inside the dielectric layer. The thermocouples are laterally disposed near the bottom of the dielectric layer. In addition, a low temperature region is formed in an area which is the overlapping of vertical projections of such thermocouples and the optical sensing part; a high temperature region is formed by the overlapping of vertical projections of such thermocouples, but without the overlaying which belongs to the vertical projection of the optical sensing part. Therefore, the system can sense the ambient light brightness, color conditions and human blackbody infrared signals within the range of 8-12 micrometers wavelength.

Abstract: In the spectroscopy module 1, a light detecting element 4 is provided with a light passing opening 4b through which light made incident into a body portion 2 passes. Therefore, it is possible to prevent deviation of the relative positional relationship between the light passing opening 4b and a light detection portion 4a of the light detecting element 4. Further, an optical element 7, which guides light made incident into the body portion 2, is arranged at the light passing opening 4b. Therefore, light, which is to be made incident into the body portion 2, is not partially blocked at a light incident edge portion of the light passing opening 4b, but light, which is to be made incident into the body portion 2, can be guided securely. Therefore, according to the spectroscopy module 1, it is possible to improve the reliability.

The present invention enables in-situ calibration and removal of the spectral signature of the background solvent from a composite spectrum so that the spectral features associated with the analyte(s) can be more easily and precisely identified.

Abstract: In a spectroscopic module 1, a flange 7 is formed integrally with a diffraction layer 6 along a periphery thereof so as to become thicker than the diffraction layer 6. As a consequence, at the time of releasing a master mold used for forming the diffraction layer 6 and flange 7, the diffraction layer 6 formed along a convex curved surface 3a of a main unit 3 can be prevented from peeling off from the curved surface 3a together with the master mold. A diffraction grating pattern 9 is formed so as to be eccentric with respect to the center of the diffraction layer 6 toward a predetermined side. Therefore, releasing the mold earlier from the opposite side of the diffraction layer 6 than the predetermined side thereof can prevent the diffraction layer 6 from peeling off and the diffraction grating pattern 9 from being damaged.
