  • Patent number: 10809185
    Abstract: An object is the provision of an optical measuring device that can be carried readily due to its reduced size and that can suppress the incidence of light other than detection light upon a light receiving unit and thus can obtain a measurement result with high accuracy. The optical measuring device includes a first light guiding path forming body having therein a first light guiding path formed by a through hole extending linearly for allowing measurement light from a light source to be incident on a measuring position in which a measurement sample is disposed, and a second light guiding path forming body having therein a second light guiding path formed by a through hole extending linearly for guiding detection light having exited from the measuring position to a light receiving unit.
