PROBLEM TO BE SOLVED: To provide a light emission quantum efficiency measuring device which easily and certainly makes isotropic the light emission of an emitter sample showing strong light emission anisotropy, and accurately measures the light emission quantum efficiency of the emitter sample. SOLUTION: This light emission quantum efficiency measuring device has: an excitation light introduction window 2 in the orthogonal direction on the plane including the center of an integrating sphere 1; and a detection probe end 3 connected to a spectrometer. The emitter sample 5 is arranged inside the integrating sphere 1 and on the line perpendicular to this plane from the center, and a baffle plate 7 is placed in a position viewing the emitter sample 5 from the detection probe end 3.

Abstract:
PROBLEM TO BE SOLVED: To provide an improved blood monitoring system and especially to reduce the cost of parts associated with a glucose monitoring system. SOLUTION: The glucose monitoring system includes a read head positioned a predetermined distance from a sample aperture. The read head comprises a first and second LEDs adapted to emit intersecting paths of light. A beam splitter is positioned at the intersection of the light paths. The beam splitter comprises a bandpass filter for controlling the center wavelength of a resulting coaxial emitted light for illuminating a sample on the sample aperture. The read head further comprises a detector which comprises a detector aperture and a molded lens over the detector aperture. A light-scattering section upstream of the lens comprises a plurality of steps having angles greater than 90° to reduce internal stray light. COPYRIGHT: (C)2004,JPO
