The LED external quantum efficiency testing system is a high-precision evaluation device that integrates advanced spectrometers, high-performance integrating spheres, and precise source meters. Coupled with professional measurement software, it can accurately measure key parameters such as LED external quantum efficiency, brightness, and electroluminescence wavelength.
The angle dependent electroluminescence (EL) measurement system can measure and analyze the luminous characteristics of LED components at different angles, mainly used to study whether LEDs belong to Lambertian radiators.
This system can effectively test the photoluminescence characteristics of materials or devices, which can meaaure photoluminesnce quantum efficiency (PLQE) of four orders of magnitude. This system is suitable for excitation and emission light of different wavelengths and intensities, and equipped with powerful testing software.
