    LQ-50X-EL: High Speed/High Sensitivity Electroluminescence Efficiency Test System

    The LQ-50X-EL is the most sensitive LED electroluminescence measurement system, capable of quickly measuring the luminescence spectrum at each voltage and obtaining multiple parameter values such as irradiance, luminance, CIE coordinates, etc. The non-repeatability of the measured inorganic LED test is less than 0.2%. It features single-photon detection technology, NIR-enhanced optical design and components and a compact product design for direct integration with glove boxes.

    Overview

    • LQ-X is super fast, time-efficient and precise photoluminescence and luminescence quantum yield measurement System with diverse functionality and can be applied to various type of light emitting materials and variety of applications to help researchers analyze the device characterization and quality.
    • LQ-X features single photon detection technology, NIR- enhanced optical design and compact footprint for direct integration with glove boxes, For light emitting devices like organic and inorganic LEDs, the respective physical value is the external quad efficiency, measured usually by electroluminescence (EL) method.
    • “Fast decay” and “Accurate evaluation of infrared emission” are most closely related to the challenges in conversion efficiency measuring.

    Key Features

    • Adopts single-photon detection technology to overcome the long exposure time (1~3 seconds) required by traditional spectrometers at low brightness, thus speeding up the test to ensure its accuracy and efficiency.
    • Adopts NIR-enhanced optical design and components to cover wavelengths up to 1100 nm, extendable to 1700 nm.
    • The LQ-50X has a compact product design for direct integration with glove boxes. At the same time, the LQ-50X is also suitable for various types of samples.
    • The LQ-50X can quickly test the luminescence spectrum at each voltage, obtaining multiple parameter values such as irradiance, luminance, CIE coordinates, etc. The non-repeatability of the measured inorganic LED test is less than 0.2%.
