HIGH-PRECISION ±0.5μm ACCURACY: Engineered for ultra-precise optical testing, this 3''x3'' resolution test chart boasts an exceptional accuracy of ±0.5μm. It provides a highly reliable standard for calibrating high-resolution cameras and lenses, ensuring your equipment captures the finest details with absolute precision. 90% LIGHT TRANSMITTANCE: Designed to maximize optical performance, the chart features up to 90% light transmittance. This high transparency dramatically improves image clarity and contrast, allowing for more accurate measurements and greater overall system stability during visual inspections. SUPERIOR FLATNESS & CHROME PLATING: The specialized chrome-plated surface effectively minimizes geometric deviations, while the superior flatness of the substrate significantly enhances calibration stability. This robust construction ensures consistent, distortion-free performance for demanding scientific and industrial inspections. NON-REFLECTIVE: Employs professional diffuse reflection surface treatment and high-contrast, low-reflection specialized materials to effectively eliminate localized highlights, stray light, and specular reflection, achieving uniform and stable light diffusion and imaging effects. WIDELY APPLIED: An essential tool across multiple fields, this test chart is extensively used for quality control, scientific research, and production line debugging. It delivers the dependable optical benchmarks needed for precise camera system calibration.
