Description

Technical Field

[0001] This utility model relates to the field of imaging luminance and colorimeter technology, and specifically to an optical performance calibration device suitable for imaging luminance and colorimeters. Background Technology

[0002] An imaging luminance-color meter is an optical instrument used to measure and analyze the luminance, chromaticity, and color distribution of an object's surface. Through an optical imaging system and a high-precision sensor, it converts the optical characteristics of the object under test into digital signals, enabling quantitative analysis of parameters such as luminance, chromaticity, color temperature, and color uniformity.

[0003] However, in the existing technology, after the imaging luminance and colorimeter is installed, the staff needs to manually calibrate the imaging luminance and colorimeter. However, the location for installing the imaging luminance and colorimeter is relatively small, and calibration requires multiple distances, making it difficult for the staff to align and calibrate the imaging luminance and colorimeter. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: an optical performance calibration device suitable for an imaging luminance and colorimeter, comprising a mounting component, a moving component, and a calibration component, wherein the moving component is disposed within the mounting component for moving and adjusting the calibration interval, and the calibration component is disposed on the moving component for adjusting the height for calibration.

[0006] Furthermore, the moving assembly includes a mounting frame, an imaging luminance and colorimeter, a slide rail, a screw, a slider, a first gear, a mounting box, a round rod, a second gear, and a first motor. The mounting frame is disposed within the mounting assembly. The imaging luminance and colorimeter is fixedly mounted on the top of the mounting frame.

[0009] Furthermore, the calibration assembly includes a connecting plate, two mounting plates, an integrating sphere, a mounting ring, a rectangular plate, a second motor, a rotating rod, a third gear, and a toothed plate. The connecting plate is fixedly mounted on the top of the slider, and both mounting plates are fixedly mounted on the top of the connecting plate.
