Abstract: According to one embodiment, a specimen detection device includes a light source, a filter, a sensor, and a controller. The light source executes a first operation and a second operation. The first operation causes a first light of a first peak wavelength to be incident on a specimen. The second operation causes a second light of a second peak wavelength to be incident on the specimen. The filter attenuates the first and second lights and transmits at least a portion of a third light and at least a portion of a fourth light. The third light is emitted from the specimen. The fourth light is emitted from the specimen. The sensor outputs a first signal and a second signal. The first signal corresponds to the third. The second signal corresponds to the fourth light. The controller calculates a result value by processing the first and second signals.
