Integrated camera solution that characterized the angular distribution of near-infrared emmission from LED and Lasers
For Near Infrared Angular Emission Measurement
Radiant Vision Systems Near Infra-Red Intensity Lens system is an integrated camera/lens solution that characterized the angular distribution of near-infrared (NIR) emissions from LEDs and lasers.
The NIR Intensity Lens measures the complete angular distribution of an NIR light source (to ±70 degrees) in a single image, and achieves an angular resolution of approximately 0.05° / CCD pixel. Paired with the ProMetric® Y16 Imaging Radiometer featuring a 16-megapixel CCD sensor, the NIR Intensity Lens has the capability to characterize radiant intensity, power, and radiant flux with a high degree of accuracy at each viewing angle. Extensive data analysis and display functions are also supported, including isometric plots, cross-sectional graphs, radar plots, and bitmaps. Learn more
