Abstract
An optical measurement apparatus can be provided, in which the sample is optically measured without loss of the illuminating light with high sensitivity. A glass plate as the transparent memberis placed in the interface between the end faceof the optical waveguideguiding the illuminating light L generated by the laser light sourceand the wall face of the capillary. According to the above feature, the air layer is prevented from existing in the interface between the end faceof the optical fiberand the wall face of the capillary, thus the sample S can be optically measured with high sensitivity and few variability without causing the loss of the illuminating light L.
