Improved performance, increased customer satisfaction, and overall lower costs for LED applications require accurate measurement of the LEDs themselves. Radiant Imaging provides the broadest array of measurement solutions for LED manufacturers and users available in the market. Radiant’s Source Imaging Goniometers - including our new SIG-400, designed specifically for LED applications - provide industry standard Radiant Source Models for use in all leading optical design software. Our Imaging Sphere provides the fastest available measurement of complete luminous intensity distribution information for LED evaluation and classification. For LED display correction and calibration, Radiant Imaging’s world leading PM-LED System provides pixel level correction for LED modules and complete signs in the factory or at location. PM-LED provides automated screen correction for superior image quality and saves money by enabling the use of less strictly binned LEDs.
