AI Technical Summary
Technical Problem
Existing goniometer-type sample stage requires manual resetting when measuring multiple positions on the sample, which increases manufacturing costs and makes it difficult to achieve flexible angle and direction movement of the sample and photodetector.
Method used
The system employs a sample holding section, a vertical moving mechanism, a horizontal moving mechanism, a yaw angle changing mechanism, and a detector rotation mechanism, combined with a motor drive, to achieve automated angle and direction adjustment of the sample and the photodetector.
Benefits of technology
It minimizes the manufacturing cost of the sample stage while automatically adjusting the sample and photodetector to various angles and directions, thus improving measurement efficiency and accuracy.

Abstract
Provided is a sample stage that can minimize increases in manufacturing costs and that can rotate a sample to various angles or move the sample in various directions. In an optical measurement device having a light source and a light detector (125), a sample stage (100) for arranging a solid sample on an optical axis (501) of measurement light from the light source to the light detector is provided with: a sample holding portion (170, 180) that holds the solid sample; an up-down movement mechanism (160) that supports the sample holding portion and moves the sample holding portion up and down; a horizontal movement mechanism (140, 150) that supports the up-down movement mechanism and moves the up-down movement mechanism in a horizontal plane; a yaw angle changing mechanism (130) that supports the horizontal movement mechanism and rotates the horizontal movement mechanism about a vertical axis; and a detector rotation mechanism (120) that rotates the light detector about the vertical axis.
