Lenses for Unique Applications and Measurement Geometries For more than 30 years, Radiant Vision Systems ProMetric® Imaging Photometers and Colorimeters have set the standard for visual inspection that matches the perception of the human eye. Now you can leverage the power of a ProMetric camera for a range of applications using lenses designed for unique applications and measurement geometries. Whether you need to evaluate view-angle performance of flat panel displays, replicate the parameters of human visualization through an AR/VR headset, or capture the angular distribution of near-infrared lasers and LEDs, Radiant has the right lens for the job.
