Abstract: In the present invention, without decreasing measurement accuracy, a biological component information measurement device can have a miniaturized device structure. In a biological component information measurement device (100), a sample container (104) accommodates a measurement target (105) such as blood, cultured cells, or urine, and a light from a light source (101) is separated into spectral components using a rotating diffraction grating (110) and caused to be incident on the measurement target (105). Due to this configuration, it is possible to reduce the number of parts of a spectral optical system and the amount of space required therefor. As a result, it is possible to, in particular, miniaturize the spectral optical system without decreasing measurement accuracy.

Abstract: A plurality of photodiodes arrayed in a one-dimensional form are divided into a plurality of groups. The structure of an antireflection coating is changed for each group so that all the surfaces of the photodiodes belonging to each group are covered with an antireflection coating having a transmittance characteristic which shows a maximum transmittance within a range of wavelengths of light to be received by those photodiodes. In particular, a SiO2 coating layer on the silicon substrate and an Al2O3 coating layer are common to all the photodiodes, while the structure of the upper layers are modified with respect to the wavelength. Within an ultraviolet wavelength region, the coating structure is more finely changed with respect to the wavelength. By such a design, the transmittance can be improved while making the best efforts to avoid a complex manufacturing process.

Abstract: An apparatus for obtaining an image of a tooth having at least one light source providing incident light having a first spectral range for obtaining a reflectance image from the tooth and a second spectral range for exciting a fluorescence image from the tooth. A polarizing beamsplitter in the path of the incident light from both sources directs light having a first polarization state toward the tooth and directs light from the tooth having a second polarization state along a return path toward a sensor, wherein the second polarization state is orthogonal to the first polarization state. A first lens in the return path directs image-bearing light from the tooth toward the sensor, and obtains image data from the portion of the light having the second polarization state. A long-pass filter in the return path attenuates light in the second spectral range.

Abstract: A Raman spectrometer optically separates an optical signal scattered by a sample from an incident excitation light beam into an unshifted return component at a first wavelength and one or more Raman scattered components at shifted wavelengths characteristic of the sample. The unshifted return component—but not the Raman scattered components—is attenuated prior to impinging on an optical detector. The unshifted return then serves as the basis for real-time calibration to account for fluctuations in optical intensity, wavelength shift, and/or spectral peak width, based on a comparison of the unshifted return peak to a reference standard for stable reflectance.

Abstract: An Echelle spectrometer arrangement (10) with internal order separation contains an Echelle grating (34) and a dispersing element (38) for order separation so that a two-dimensional spectrum having a plurality of separate orders (56) can be generated, an imagine optical system (18, 22, 28, 46), a flat-panel detector (16), and predispersion means (20) for predispersing the radiation into the direction of traverse dispersion of the dispersion element (38). The arrangement is characterized in that the predispersion means (20) comprise a predispersion element which is arranged along the optical path behind the inlet spacing (12) inside the spectrometer arrangement. The imaging optical system is designed in such a manner that the predispersed radiation can be imaged onto an additional image plane (24) which does not have any boundaries in the predispersion direction and which is arranged along the optical path between the predispersion element (20) and the echelle grating (34). Optical means (20, 68) in the area of the predispersed spectrum are arranged to influence the spatial and/or the spectral beam density distribution on the detector (16).

Abstract: A spectrometer can include a plurality of semiconductor nanocrystals. Wavelength discrimination in the spectrometer can be achieved by differing light absorption and emission characteristics of different populations of semiconductor nanocrystals (e.g., populations of different materials, sizes or both). The spectrometer therefore can operate without the need for a grating, prism, or a similar optical component. A personal UV exposure tracking device can be portable, rugged, and inexpensive, and include a semiconductor nanocrystal spectrometer for recording a user's exposure to UV radiation. Other applications include a personal device (e.g. a smartphone) or a medical device where a semiconductor nanocrystal spectrometer is integrated.
