Saelig Introduces LED Reference Luminance Standard

Fairport, NY, USA: Saelig Company, Inc. (www.saelig.com) has introduced the patent-pending GL OptiLight LED 127 with ability to control the properties of its LEDs using a complex multilevel calibration procedure that characterizes each individual LED light source, storing the spectral properties in the unit’s electronic controls.

The GL OptiLight LED 127 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 excellent light source homogeneity. It features an electronic control system and thermal stabilization in order to achieve remarkable color stabilization.

The GL OptiLight LED 127 can create almost any color source when controlled by a PC via USB connection or set with the LED control panel. The ‘adJUST‘ software supplied allows a wide range of light coordinates to be set 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 consists of the basic factory calibration and the permanent on-line operational calibration, therefore not requiring an external metrological device. The GL OptiLight LED 127 effectively self-controls its operating conditions and adjusts the resultant lighting with a high frequency drive (>100Hz), which is both permanent and invisible to the human eye.

The LED technology used in GL OptiLight LED 127 not only exceeds conventional LED sources in light quality, creating almost any light coordinates with high quality, but can now for the first time accurately reproduce a tremendous color space on demand.

Key features:

Very high uniformity
Near perfect replication light sources like D50, D65, D75, A, and TL84
Free selection of light spectra out of color space bigger than sRGB
Stable conditions through a unique calibration method
Very long LED lifetime due to active thermal stability
