Ambient Light Photo Sensors (ALPS) – are used to measure the ambient light level in the environment as perceived by the human eye. It is designed to detect bright and dim ambient light conditions as a means of controlling the brightness of LCD display and/or keypad backlight.

ATEC is capable to assemble Ambient Light Photo Sensors in micro DFN package with index of refraction more than 1.5, 97% transmission at 850uM wavelength, and at a maximum operating temperature of 110°C.
