Luminoscopic analytic device and method

摘要

An analytic device (1) for reflective luminoscopy comprises within an enclosure (11): a light source (12); a pair of spaced light detectors (141, 142); and a refractor body (16); the refractor body comprises a planar base (161), an entry plane (163) near the light source for light emanating therefrom, and an exit plane (165) near the spaced detectors for light that is being sensed by at least one of the detectors; the entry plane and the exit plane enclose an angle of less then 180 DEG and not less than 90 DEG , the enclosure further includes a light-collimating means or lens (13) between the light source and the entry plane; a light-collecting means or lens (15) between the light detectors and said exit plane, and at least one light-reflecting surface (171) near the planar base (161); at least one luminoscopic layer (191) normally comprising a luminoscopic indicator and a thin transparent carrier, is arranged between the planar base and the at least one light-reflecting surface; the device includes both a luminoscopic reference as well as a measuring area for a luminoscopic reaction between a luminoscopic layer and a species of analytic interest.
