PROBLEM TO BE SOLVED: To provide a light-emission detecting device which stably joins substrates having projecting/recessed portions each other, and prevents unnecessary light-emission from reaching detecting means.SOLUTION: A light-emission detecting device 20 has a channel 3 configured by bonding two substrates 16 and 17, and detects the light-emission from the channel. A detecting side substrate 16 having a bonding surface on which recessed portions becoming a part of a wall surface of the channel and a light-shielding film 1 disposed on an area other than the recessed portions are disposed, and a detection surface 6 which is disposed on the back surface of the bonding surface, and making the light-emission from the channel pass through to be detected; and a wiring side substrate 17 disposing a conductive pattern 4 having the thickness of projecting portions and recessed portions on a surface bonded with the detecting side substrate are bonded with each other. In the area in which the light-shielding film is disposed, an adhesive material 7 is disposed according to the thickness of the projecting portions and the recessed portions of the conductive pattern 4, and the detecting side substrate and the wiring side substrate are tightly joined by the adhesive material.

PROBLEM TO BE SOLVED: To provide a fluorescence detecting apparatus for achieving miniaturization and cost reduction and accurately detecting the position of a fluorescence material in a measurement object using an image. SOLUTION: The fluorescence detecting apparatus 100 includes: an excitation light emitting section 1 for emitting excitation light onto the measurement object 20; an illumination light emitting section 2 for emitting illumination light onto the measurement object 20; an imaging apparatus 50 that has an excitation light blocking section 5 for blocking light of the wavelength band of the excitation light and images light from the measurement object 20; and a control section 8 for controlling the imaging apparatus 50, the excitation light emitting section 1, and the illumination light emitting section 2. The control section 8 makes the excitation light emitting section 1 emit the excitation light onto the measurement object 20, defines an imaging condition of the imaging apparatus 50 based on imaging results to be taken by imaging light from the measurement object 20 by the imaging apparatus 50, defines an illumination condition of the illumination light, makes the excitation light emitting section 1 and the illumination light emitting section 2 emit the excitation light and illumination light onto the measurement object 20, and makes the imaging apparatus 50 image the light from the measurement object 20.

Abstract:
PROBLEM TO BE SOLVED: To provide a plate for examination capable of conducting exactly fluorometry for determining the presence of a biochemical reaction, for example, between a probe DNA and a specimen DNA. SOLUTION: Light shielding parts 16, 16 are provided along a flow passage 13 in a sideway of a graphically shown X1 side (right side) and in a sideway of a graphically shown X2 side (left side) of the flow passage 13, on a surface 11a of a plate substrate 11. Lights emitted slightly from the plate substrate 11 and a lid 12 are properly shielded by the light shielding parts 16, 16, in this manner, when measuring fluorescence intensity for determining the propriety of the reaction of the specimen, so as to enhance stability in the measurement of the fluorescence intensity with respect to each bead arrayed inside the flow passage 13.
