Abstract:
A fluorescence detection apparatus is provided which comprises a sample holder for holding stationarily sample vessels deployed along a circle line or concentric circle lines having different radiuses, a partition plate connected to a driving means to be rotatable around the center of the circle line or concentric circle lines, an optical means for excitation light and an optical means for fluorescence light fixed respectively to the partition plate to be rotatable in integration therewith, a first light guide constituted of numerous optical fibers, a photosensor, and a light source for generating the excitation light, wherein the partition plate, the optical means for excitation light, and the optical means for fluorescence are integrally rotated, and thereby the fluorescence of the sample arranged along the circle line is successively detected and the detected fluorescence is transmitted to the photosensor. This fluorescence detection apparatus is useful in real-time monitoring of fluorescence signals, and satisfies the requirements of precise temperature control, quick treatment of many samples, high sensitivity, high reliability, low cost, and small size of the apparatus.
Abstract:
There is presented a multipoint measurement system comprising light sources (1, 2); a plurality of illuminating fibers (5, 6) for transmitting light from the light sources to a sample so as to illuminate a plurality of points of the sample (A, B); a plurality of receiving fibers (8, 9) for collecting light beams including transmitted, reflected, scattered light beams at the plurality of points; a beam selector (10) which comprises a rotatable disk (12) having an aperture for transmitting a light beam collected by one of the plurality of receiving fibers (8, 9) through the receiving fiber (11); and an MCPD (4). When the rotatable disk (12) is rotated so that the aperture is displaced to and stops at a position at which light at the desired channel passes through, it is possible to perform measurement only on the light passing through the corresponding receiving fiber (8, 9, 11). Light at any other channel may be measured by rotating the rotatable disk (12) by a predetermined angle.

PROBLEM TO BE SOLVED: To provide a multipoint measuring apparatus by which a plurality of points are simultaneously measured by selecting and changing over an optical path even when only a single measuring channel of an optical measuring device exists. SOLUTION: The multipoint measuring apparatus is provided with a light source 1 and a light source 2; a plurality of projection fibers 5, 6 used to irradiate beams of light from the light sources at the plurality of points; a plurality of light receiving fibers 8, 9 used to collect beams of transmitted light, reflected light, scattered light and the like from the plurality of points; a beam selector 10 composed of a rotating disk 12 having one transmission hole used to pass the beams of light collected by the plurality of fibers 8, 9 to any one light receiving fiber; and an MCPD 4. Consequently, when the rotating disk 12 is turned and when the transmission hole is brought to, and made at a standstill in, a position passing the beams of light in a channel to be measured, the beams of light in the light receiving fiber are transmitted and measured. When the beams of light in other channels are measured, the rotating disk is turned by a prescribed angle. COPYRIGHT: (C)2004,JPO
