OrderableCS140 Calibrator
Overview
The CS140 Calibrator is a high-quality device to generate a known luminance level for calibrating a CS140 Background Luminance Sensor. It is powered from the CS140 supply and is used while in communication with it.
Key Advantages
Technical Description
The calibration is made by using high-quality LEDs to produce a known light level, white, with a value of 4500 cd/m2. The light has a flat spectrum so the calibration is valid over the CIE spectrum sensitivity of the CS140 itself. The LEDs illuminate a diffuser, which itself illuminates the CS140 under calibration. An on/off switch turns off the LEDs and allows the unit to provide a zero check. Each unit is individually calibrated, and the value of luminance it produces is put on a label on the unit. This calibration is traceable, and this value is used in the calibration process.
