MEASURING METHOD FOR IMMUNOCHROMATOGRAPHIC TEST STRIP

摘要

A measuring device (1) comprises a projection optical system (20) and an optical system (30) for detection. The optical system (20) includes a light-emitting device (21) and a mixing rod (22). The optical system (30) includes a cylindrical lens (33) and a CCD image sensor (36). The light from the light-emitting device (21) is diffused by a diffuser (23), introduced to the mixing rod (22), and mixed. The light mixed by the mixing rod (22) is diffused by a diffuser (24), and directed as measurement light toward an immunochromatographic test strip (10). The light through the immunochromatographic test strip (10) passes through the cylindrical lens (33) to form an image on the photodetector surface (37) of the CCD image sensor (36). The CCD image sensor (36) photographs the image formed on the photodetector surface (37).
