JY-iphS-E light source spectrum adjustable: from simulating real scenery to high-precision calibration
JY-iphS-E Spectral Adjustable Uniform Extended Light Source simulates various spectral distributions in the visible near-infrared band by mixing more than thirty monochromatic LED and tungsten halogen lamp light sources (or xenon lamp light sources) in an integrating sphere, such as CIE A light source, B light source, C light source, D65 light source, E light source, grassland spectrum, forest spectrum, desert spectrum, and seawater spectrum, etc., obtaining a uniform radiation light source with adjustable spectra. The spectral radiation monitor based on spectrometer can display and control the output spectral radiance in real time, and the software will also display the matching error between the output simulated spectrum and the target spectrum in real time. Unit probes based on unit detectors are used to detect system output stability.
Product advantages: The full band integrated radiance can reach 120W/(m ² sr) @ (400nm~900nm), and the output spectral distribution can be tuned and color adjusted, achieving spectral radiance output close to real scenery. Based on monochromatic LED with the same color and spectrum and wide color gamut simulation, it can be used for color calibration of optical remote sensors with a high stability radiance output of 0.5%/2h, meeting the requirements of long-term high stability calibration process. 98% of the radiance uniformity and 98% of the angle (Lambertian) uniformity provide high-quality Lambertian surface light source calibration traceable to the National Institute of Metrology (NIM) in China, and provide metrological calibration report software for monitoring and outputting spectral radiance and chromaticity information
