Abstract:
A light amount is increased and an analyzing accuracy can be kept in accordance with an enlargement of a load angle, however, a scattered light tends to be loaded in an analysis accompanying the scattered light and a dynamic range of a concentration which can be measured becomes narrow. A light is dispersed by a light dispersing portion, a load angle of the received light is changed per wavelength, the load angle is made larger in the light of a wavelength having a small light amount, and the load angle is made smaller in the light a wavelength having a large light amount and used for an analysis accompanying a scattered light. Accordingly, it is possible to gain a dynamic range of a concentration which can be measured in the analysis accompanying the scattered light, while increasing the light amount and maintaining the analyzing accuracy.
Abstract:
This invention provides a multiphoton excitaion microscope for simultaneously detecting differently colored fluorescence materials on biochips, which includes a multiphoton excitation source, objectives, and a plurality of detection channels. The biochip is hybridized and labeled with fluorescence materials for expressing hybridized biological signals. The multiphoton excitation source is focused to a light spot on the biochip to excite the fluorescence materials bound thereon. After that, the fluorescence emission at different wavelengths from the different fluorescent materials can be detected by the plural detection channels.
Abstract:
There is provided a data processing apparatus including: a data determination portion that specifies, in each of first and second light intensity distribution data, an analysis range corresponding to a storage area for storing a detection target, the first and second light intensity distribution data being acquired on the basis of light emitted from first and light sources to a detection area; and a mode selection portion that selects an operation mode of the data determination portion. The mode selection portion selects one of a first mode in which the data determination portion specifies the analysis range in each of the first light intensity distribution data and the second light intensity distribution data, and a second mode in which the data determination portion specifies the analysis range in the second light intensity distribution data on the basis of information on the analysis range of the first light intensity distribution data.
Abstract:
L'analyseur automatique comprend un support (5) rotatif portant les cuves (6) dans chacune desquelles est opéré le mélange dosé d'une quantité d'échantillons avec une quantité de réactif. Le support (5) amène chacune des cuves (6) en relation optique avec un moyen d'analyse constitué de plusieurs modules (9A). Chaque module comprend d'un côté du trajet des cuves (6), une terminaison lumineuse (13) et de l'autre côté dans l'axe du rayon émis par la terminaison lumineuse (13) un filtre interférentiel (11) et un photodétecteur (12). Chaque module (9A) comporte son propre filtre différentiel (11) et est traversé successivement par chaque cuve (6), ce qui donne autant de mesures différentes qu'il y a de modules. De plus, les cuves (6) sont espacées les unes des autres de manière à ce que chaque module (9A) puisse opérer sa prise de mesure de référence lorsque le rayon lumineux traverse l'intervalle entre deux cuves.
Abstract:
An optical detection apparatus which is capable of measuring a sample is provided. The optical detection apparatus includes a plurality of light emission units, a light receiving unit, a driving unit, and an analyzing unit. Each of the light emission units is capable of emitting a light beam. The light receiving unit is capable of receiving the light beam passing through the sample and is capable of converting the received light beam to an electrical signal. The driving unit is capable of changing the relative position of the light emission units and the sample. The analyzing unit is electrically connected to the light receiving unit and is capable of measuring a property of the sample by using the electrical signal. A number of the light receiving unit is less than a number of the light emission units. An optical measurement system including the optical detection apparatus is also provided.
Abstract:
A device for the photometric examination of samples has a sample-holder apparatus for at least two sample vessels, and a measuring apparatus and a moveable apparatus. The sample-holder apparatus is designed to be stationary, and the measuring apparatus is arranged on the moveable apparatus such that it can be displaced by means of the moveable apparatus.
Abstract:
A spectrophotometric optical system of a microplate reader and a filter wheel thereof are disclosed. The filter wheel comprises a pivotable wheel body, at least one narrow-band filter with a relatively long central wavelength mounted to the wheel body, and at least one narrow-band filter with a relatively short central wavelength mounted to the wheel body. The narrow-band filter with a relatively long central wavelength is provided with a diaphragm on a front surface thereof The diaphragm is formed with a plurality of apertures. By the diaphragm attached to the front surface of the narrow-band filter with a relatively long central wavelength, an energy matching between light of longer wavelength and light of shorter wavelength may be achieved. Further, due to the uniformly distributed apertures in the diaphragm, an even light spot may be obtained.

Abstract:
An automatic analyzer of a single-line and multi-item type having a circular reaction line along which a number of reaction vessels are transported in the stepwise manner, and a photometering apparatus in which white light is divided into a plurality of light beams having different wavelengths, by means of a diffraction grating, and the light beams are transmitted by means of light guides whose exit ends are arranged along the reaction line with a pitch which is different from that with which the reaction vessels are arranged. While the reaction vessels are moved by one pitch, a plurality of reaction vessels are photometered in time sequential manner.
