Abstract
Provided is a concentration measurement device that includes a light source that emits light, a first optical system that is provided on an optical path of the light emitted from the light source and condenses the light emitted from the light source, a light-transmissive tubular body that is disposed at a position on a rear stage side with respect to a focal position of the first optical system on the optical path and collimates the light incident on a side surface in a state where a fluid flows inside, and a detection unit that detects light through the tubular body.
Claims9
A concentration measurement device, comprising:
- a light source configured to emit light;
- a first optical system configured to condense the emitted light, wherein
- the first optical system is on an optical path of the emitted light;
- a light-transmissive tubular body configured to collimate the condensed light incident on a side surface of the light-transmissive tubular body, wherein
- a fluid is inside the light-transmissive tubular body, and
- the light-transmissive tubular body is at a position on a rear stage side with respect to a focal position of the first optical system on the optical path;
- and
- a detection unit configured to detect the light through the light-transmissive tubular body.
