Abstract: A compact device useful for measuring an absorption spectrum of a liquid, such as water with organic contaminants, is provided. The device comprises an array of light emitting diodes (LEDs) each emitting light with a unique spectral peak. A reflector shaped as a half ellipsoid reflects the emitted light to form a reference beam. The reflector has an opening to allow part of the emitted light to form a measurement beam after passing through the liquid. Two photodetectors measure the reference beam and the measurement beam to give a reference intensity and a measured intensity, respectively. The LEDs sequentially emit showers of light one-by-one, giving plural pairs of reference and measured intensities for estimating the absorption spectrum. The device receives energy from a separate power-providing device through wireless power transfer. The power-providing device harvests motional energy of the flowing liquid to generate electrical energy.

Abstract: A spectroscopic measuring device includes a halogen lamp as a light source, a lens of an irradiating system, a mirror, and a spectrometer. The lens of the irradiating optical system emits light from the halogen lamp to a measurement object. The mirror is an optical member, and the mirror is arranged coaxial with the lens and conducts detecting light between the halogen lamp and the measurement object, to the spectrometer. The spectrometer is an analyzing part and analyzes material of the measurement object on the basis of the light received via the mirror. The light from the halogen lamp to the measurement object passes through the peripheral part of the optical axis of the lens, and the light to be received by the spectrometer passes through the center part of the optical axis of the lens, at the position of the mirror.

Abstract: A device including an optical measuring device and an optical system which can measure the light intensity of the scattered light from the sample and the spatial distribution of the scattered light and which is excellent in the sensitivity is provided. In the device, the image distortion is suppressed by providing such a structure that the light emitted from the first substance is reflected by the ellipsoidal mirror two or more even times before reaching the second substance. The image distortion is suppressed by arranging two ellipsoidal mirrors so that respective one focuses are set to a common focus while remaining other two focuses are arranged on one line so as to be opposite to each other across the common focus, setting the common focus to a blank, arranging a first substance on one of the focuses, and arranging a second substance on the other of the focuses.

Abstract: Objectives and other optical assemblies include a reflective surface that is truncated at or near a focus based on a curvature of the reflective surface. A specimen is situated at or near the focus of the reflective surface, so that the reflective surface captures and collimates optical radiation emitted from the specimen. The reflective surface can be defined on an optical substrate along with a lens surface, so that an illumination flux is focused on the specimen by the lens surface, and a secondary light flux produced in response to the illumination flux is captured and collimated by the reflective surface.

Abstract: The present invention involves an apparatus for detection of laser-induced fluorescence, wherein a sample substrate is made of transparent or semi-translucent materials and the apparatus is equipped with a reflector that reflects the reflected light from the sample and the scattered light of the excitation light; a focusing system that collects light transmitted through the sample; a spatial filter that eliminates noise component from the reflected light from the reflector and/or output from the focusing system; a collimator that converts the light passed through the focusing system to a parallel light; a fluorescence filter that filters only the fluorescence from light transmitted through the collimator; and a photodetector that converts the output light from the fluorescence filter into the electric signal. The present apparatus may further be equipped with an optical feedback system that is placed in the rear of the sample and sends light transmitted through the sample back to the sample. Therefore, the apparatus according to the present invention provides higher light focusing efficiency and improved utility of the excitation light energy by recycling the transmitted light to increase the fluorescence yield, as compared with the conventional system.
