Multi-Reflectivity Grayscale Plate

Multi-reflectivity grayscale chart is a standard measurement tool used for calibration and performance evaluation of machine vision, industrial cameras, optical inspection, and imaging systems. The product typically consists of multiple grayscale regions with different standard reflectivities. By providing continuous or graded grayscale references from low to high reflectivity, it enables the testing and calibration of the response characteristics of imaging systems under different brightness conditions.

Multi-reflectivity grayscale charts feature clearly defined reflectivity levels, stable grayscale gradients, and good surface consistency. They can be used to evaluate the dynamic range, grayscale response, exposure performance, linearity, and image consistency of cameras, and can serve as a standard reference for image processing algorithms and visual inspection systems.

1. Main Features
High uniformity and high precision; capable of generating multi-fusion reflectivity images with a reflectivity division value of 1%, while maintaining image accuracy and uniformity; customizable large sizes are available.

(1) Multiple Reflectivity Levels: Covers different grayscale ranges, providing multi-level standard reflectivity references for the system.

(2) Stable Reflectivity: Employs stable standard materials and surface treatment processes to ensure the consistency of measurement results.

(3) Uniform Gray Scale: Uniform color and reflectivity across all areas reduces the impact of surface differences on test results.

(4) High-Precision Manufacturing: Strict control over the size, position, and reflectivity parameters of each grayscale area.

(5) Wide Applicability: Can be used for performance testing of cameras, lenses, light sources, and image acquisition systems.

(6) Customization Support: Reflectivity levels, dimensions, grayscale quantity, and panel layout can be customized according to customer needs.

2. Typical Applications

Includes machine vision system calibration, industrial camera grayscale response testing, HDR and dynamic range testing, exposure and linearity evaluation, image quality inspection, and performance verification of optical imaging systems.
