Abstract
The present invention intends to enable light path length to be kept the same between sample measurement and reference measurement and thereby improve measurement accuracy, and is an optical analyzer that analyzes a sample flowing through a pipe having translucency. In addition, the optical analyzer includes: a light source unit that has a light source and a condenser lens; a light detection unit that detects light of the light source unit; and a support mechanism that movably supports the light source unit and the light detection unit. Further, the support mechanism moves the light source unit and the light detection unit between a sample measurement position and a reference measurement position.
Claims7
An optical analyzer that analyzes a sample flowing through a pipe having translucency, the optical analyzer comprising:
- a light source unit that has a light source and a condenser lens;
- a light detection unit that detects light of the light source unit;
- and
- a support mechanism that movably supports the light source unit and the light detection unit,
- wherein the support mechanism is one that moves the light source unit and the light detection unit between a sample measurement position allowing the light detection unit to detect the light of the light source unit via the pipe and a reference measurement position allowing the light detection unit to detect the light of the light source unit without the pipe, and further comprising
- a reference optical member positioned between the light source unit and the light detection unit in the reference measurement position, wherein
- the support mechanism further comprises:
- a fixedly provided base member;
- and
- a connecting member that connects between the light source unit and the light detection unit;
- and
- a slide drive part that is provided on the base member and slidingly moves the light source unit and the light detection unit with respect to the base member, the light source unit and the light detection unit being connected by the connecting member, wherein
- the connecting member is formed with an optical member avoiding part so as to avoid interference with the reference optical member when the light source unit and the light detection unit are moved to the sample measurement position.
