Imaging Spectroradiometer


Optical Test Instrument of Display Devices

LUMO is a product series of spectroradiometers optimized for display testing. The basic functions of the spectroradiometer measures spectral radiance and automatically calculates luminance and chromaticity. It includes variable aperture size, object focusing, optical alignment and viewfinder monitoring. The display test requires combinations of special measurement functions related to display response and transient. LUMO® series is compatible with DeJign® and other environmental systems, and it can share an interface with Window PC and Android Tablet.
