Title:
APPARATUS FOR MEASURING OPTICAL PATH LENGTH
Document Type and Number:
Japanese Patent JP3965831
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain an optical path length in a depthwise direction of a sample stored in a container.
SOLUTION: With a laser light 9 being irradiated by a laser light source 11, the laser light source 11 is moved by a light source-driving mechanism 13 to move an irradiation position of the laser light 9 to a well 1a to a perpendicular direction. A scattering light 23 is generated in a direction orthogonal to the laser light 9 at a position where a sample 3 is present. No light is generated in the direction orthogonal to the laser light 9 at a position where the sample 3 is not present. The scattering light 23 is detected via a pin hole slit 8 by a photo detection sensor 7a. A position of a liquid face and a position of a liquid bottom of the sample 3 stored in each well 1a are detected on the basis of a detect signal of the photo detection sensor 7a and an X coordinate of the laser light source 11, and moreover, an optical path length in a depthwise direction of the sample 3 is calculated.
