Abstract
The present invention is to provide a diffracted light removal slit and an optical sample detection system including the same, in which diffracted light of excitation light can be reliably removed without affecting reflected light of the excitation light in a sample detection device utilizing the reflected light of the excitation light. A diffracted light removal slit is provided between a light source unit and an excitation light reflector in an optical sample detection system that emits excitation light from the light source unit and also performs predetermined measurement using reflected light of the excitation light reflected at the excitation light reflector. The diffracted light removal slit includes: a main portion provided in a direction substantially perpendicular to an optical path of the excitation light; and a sidewall portion extending from an end portion of the main portion and inclined toward an upstream side in an optical path direction of the excitation light.
