Environmental light sensors use the human eye's method to detect brightness, and they are used to adapt the system to environmental light like the human eye in any situation. Intelligent sensors can predict indoor and outdoor ambient light and provide corresponding feedback and correction. To achieve these functions, an intelligent calibration light source is required.
The Trulume series ALS-1000 adjustable ambient light sensor calibration light source ALS-1000 from Lanfei Optics is a sensor calibration solution.
The ALS-1000 uses uniform standard brightness and chromaticity light sources instead of multiple light sources and comparison steps in traditional spectral response testing, simplifying the process and greatly improving the production testing efficiency of ambient light sensors

Application field

• Calibration of smartphone ambient light sensor
• Automatic white balance
