ABSTRACT:
A measuring plate for use in a sensor utilizing the phenomenon of attenuation in total internal reflection provides a dielectric block and a film layer and includes a dielectric plate provided with a plurality of recesses each provided with a film layer and holding a sample in contact with the film layer, and a reflecting optical system including a reflecting surface which is formed on the dielectric plate for each of the recesses to cause the light beam emitted from the light source to impinge upon the interface between the film layer of the recess and the dielectric plate and/or to cause the light beam reflected at the interface between the film layer of the recess and the dielectric plate to travel toward a predetermined position.
