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.

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: An apparatus for imaging a tooth has at least one illumination source for providing an incident light having a first spectral range for obtaining a reflectance image of the tooth and a second spectral range for exciting a fluorescence image of the tooth. A first polarizer having a first polarization axis and a compensator in the path of the incident light of the first spectral range are disposed to direct light toward the tooth. A second polarizer is disposed to direct light obtained from the tooth toward a sensor and has a second polarization axis that is orthogonal to the first polarization axis. A lens is positioned in the return path to direct image-bearing light from the tooth toward the sensor for obtaining image data. A filter in the path of the image-bearing light from the tooth is treated to attenuate light in the second spectral range.

Abstract: A scanner device includes a color measuring, a support surface for a measured object and a drive unit for moving the measuring head across the support surface and for adjusting the height of the measuring head in a direction perpendicular to the support surface. The measuring head is equipped with an illuminating channel and a collection channel. The illuminating channel has a light source and optical means for illuminating the measured object at a measurement site at a mean angle of incidence of 45°. The collection channel has optical means for capturing light emanating from the measured object at the measurement site at a mean collection angle of 0° and coupling it into a light guide, which directs the captured light to a wavelength-selective photoelectric transformer, which resolves it into a number of wavelength ranges and generates an electric measurement signal corresponding to each wavelength range.

Abstract: The present invention relates to a method and system of array imaging that extends or maximizes the longevity of the sensor array by minimizing the effects of photobleaching. The imaging system has a light source, a variable exposure aperture, and a variable filter system. The system extends the longevity of sensors by (1) using the variable exposure aperture to selectively expose sections of the sensor array containing representative numbers of each type of sensor, and/or (2) using the variable filter system to control the intensity of the excitation light, providing only the intensity required to induce the appropriate excitation and increasing that intensity over time as necessary to counteract the effects of photobleaching.
