Ultra-High Illumination Flickering Lightbox

SphereOptics Lichtbox08 July 2024 - The LED Lightbox ILB-B-150K from SphereOptics partner Imatest produces uniform light with excellent spectral characteristics that can be adjusted over a wide range of brightness for illuminating transparency test charts for image quality testing. Furthermore, it can also be used without any test charts to serve as a source of uniform irradiance that can be utilized for several radiometric test and calibration purposes.

This lightbox, with a 5100 K visible spectrum, is brighter than outdoor direct sunlight. With a luminance of 10 to 47 700 cd/m2 (30 to 150,000 lux) it is also superior lighting to other LED or fluorescent systems. Over an active area of 260 x 220 mm, it grants a uniformity of 95% and for 300 x 280mm still 90%. Furthermore, it has a flickering option that can be utilized for IEEE P2020 testing of camera LED flicker mitigation (LFM). Additional to this, the lightbox can be equipped with a wireless communication module, which enables a greater flexibility in the installation and placement of the device.
