Abstract

PURPOSE:To prevent the reflection of propagated exciting light at an emitting end surface and to perform highly accurate measurement based only on optical characteristics by forming a light absorbing layer to the surface of the output end of an optical waveguide. CONSTITUTION:A measuring apparatus is constituted of a slab type optical waveguide 1 having a wedge-shaped prism 12 symmetric with respect to an optical axis BS integrally molded only at one end part thereof and a casing 2 receiving said waveguide 1 and the surface of the light emitting end of the waveguide 1 crosses the optical axis BS at a right angle and is covered with a light absorbing paint layer 16. The exciting light emitted from an exciting light source is guided to the prism through a dichroic mirror 4 and a solution to be examined containing an antigen and a fluorescent labelled antibody 32 are received in the casing 2. The exciting light is refracted by the prism to be introduced into the optical waveguide main body 11 to propagate while totally reflected and further propagated to the side surface of the emitting end to be absorbed by the paint layer 16. Since the reflected component of the exciting light is certainly removed to be not incident to a detector 5, highly accurate measurement based only on optical characteristics can be performed.
