GL Optic has created a patent-pending product with ability to control the properties of its LEDs using a complex multilevel calibration procedure that characterizes each single LED light source, storing the spectral properties in the unit's electronic controls. The GL OPTI LIGHT LED 127 CLC (closed-loop analog feedback control) can be used as a reference luminance standard for display and monitor calibration systems as well as a reference for calibrating cameras and other optical instruments. The system combines a set of LEDs with an integrating sphere providing ideal light source homogeneity. It features a stable electronic feedback control system that produces light without any flicker associated with other light sources, which, together with built-in thermal stabilization, achieves remarkable color stabilization.
The GL OPTI LIGHT LED 127 CLC can be controlled by a PC via USB connection to create almost any color source. Alternatively, the settings can be set with the LED control panel. The available “Adjust” software is a recommended option which allows light coordinates to be preset according to the user's needs. Several light source standards are also featured, including D50, D65, D75, A, and TL84.
The active multilevel calibration system is divided into the basic factory calibration and permanent on-line calibration during operation without using an external metrological device. The GL OPTI LIGHT LED 127 CLC effectively self-controls its operating conditions and adjusts the light result with reproducible stability.
The LED technology used in GL OPTI LIGHT LED 127 CLC not only exceeds conventional LED sources in light quality, but is now for the first time able to replicate a tremendous color space with the highest quality. http://www.saelig.com/MFR00137/M00137002.htm
