Title:
ABSORPTIOMETRY DEVICE AND BIOCHEMICAL ASSAY DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2023/008158
Kind Code:
A1
Abstract:
The present invention enables detection of the quantity of light necessary for sample identification in a photoreceiver. For this purpose, the present disclosure proposes an absorptiometry device comprising: a plurality of LEDs; a baseplate provided with the plurality of LEDs in the same plane; a lens into which light emitted from the plurality of LEDs directly enters; a slit through which penetrant light passes, said light having traversed the lens, entered a reaction cell and penetrated through the reaction cell; and a photoreceiver that receives the penetrant light and converts same into an electric current. In an effective area on the baseplate where light can reach the slit, the plurality of LEDs are arranged in order of increasing parameter values computed on the basis of LED output, light-emitting surface area, and wavelength full width at half maximum, and also so that the LED exhibiting the smallest parameter value contains the optical axis that passes through the center of the lens and the center of the slit (see Fig. 2).
