  • DUAL-DIAL MEASUREMENT DEVICE AND MEASUREMENT METHOD FOR VIEWING ANGLE MEASUREMENT OF OPTICAL COMPONENT
    Publication number: 20230375438
    Abstract: A double-dial measurement device and a measurement method for viewing angle measurement of an optical component are provided. The device includes a support frame, a large dial, a small dial, a vernier disc, verniers and an objective table. When the first locking knot is fastened and the small dial rotates, the large dial or the vernier disc are driven to rotate synchronously, which refers to a rotation motion centered on an axis of the large dial under external force. When a symmetrical light source is irradiated on the optical component, an exit angle of exit lights is used to measure the viewing angle, effectively measuring the effective viewing angle of a single optical component and an optical component set, evaluating the optical component or system with reference to the viewing angle, and providing guidance and reference for the optical component.
