Luminance & Chromaticity Uniformity Analyzer

U.S.-based sales, and delivery available. The UA-20C 2D luminance and chromaticity uniformity analyzer features a 24.5-megapixel CMOS sensor for high-resolution display and lighting evaluation. Designed for production line integration, it supports 0.01–50,000 cd/m² measurement (up to 500 million cd/m² with ND filter). Ideal for Mura inspection, automotive displays, AR/VR panels, Micro LED devices, and LED lighting uniformity testing. Compact, lightweight, and equipped with GigE interface and external control SDK for automated inspection systems.
