OPTICAL INSPECTION DEVICE

摘要

An optical inspection device which, when optical changes such as white turbidity/white sedimentation are caused in a sample as a result of a reaction for amplifying an object of inspection existing in a sample tube, arranges upright sample tubes in a plurality array holes formed in a reaction block, applies an inspection light to each sample tube through an observing through hole formed in its side surface or a through hole formed in its bottom surface, and detects optical changes such as white turbidity/white sedimentation produced in sample tubes based on the luminance distribution or chromaticity distribution of image data picked up by an imaging camera to accurately and quickly be able to inspect the presence of an object of inspection.
