Abstract: To accurately measure chromaticity and turbidity while achieving downsizing and employing a turbidity measurement method based on water quality standards of each country, an optical measurement includes a cell that accommodates a liquid sample, a transmitted light measurement light source that irradiates the liquid sample in the cell with light for transmittance, a scattered light measurement light source that irradiates the liquid sample in the cell with light for scattering, a photodetector that detects light from both sources, and a reflection mirror that reflects the light for transmittance in the cell to cause the light for transmittance to be directed to the photodetector. The scattered light measurement light source emits the light for scattering toward a post-reflection optical path of the light for transmittance reflected by the reflection mirror and directed to the photodetector so that the light for scattering intersects the post-reflection optical path at a predetermined angle.

Abstract: A pathogen detection apparatus includes an obtainer that measures a body temperature of a subject and outputs information indicating the body temperature, a collector that performs a pathogen collection operation for collecting a pathogen carried by the subject or a pathogen in air around the subject, a detector that performs a pathogen detection operation for detecting the pathogen collected by the collector, a notifier that provides a notification indicating a detection result obtained by the detector, and a controller. In a case where the body temperature output by the obtainer is higher than a predetermined threshold value and the detection result obtained by the detector is negative, the controller controls the detector to perform another pathogen detection operation for detecting a pathogen.
