LED Near-Field Goniophotometers

GO-NR1000 is applicable for near-field photometric measurement of small-size light sources(LED, etc.). It can obtain the luminance distribution by establishing the ray model of light via algorithm to get total luminous flux, illuminate distribution of every plane, and far-field luminous intensity distribution. Combinations of ray model and optical software (Tracepro, etc.) offer more convenient and accurate methods for secondary optical design and development.
