Abstract
An integrated semiconductor optoelectronic component for sensing ambient light levels includes a silicon photomultiplier configured to deliver an output signal indicative of the intensity of the light that irradiates the component. The silicon photomultiplier has an active surface area for light detection. The component also includes an optical filter covering the active surface area of the silicon photomultiplier. The optical filter is adapted to selectively transmit light onto the active surface area as a function of wavelength. The optical filter is a scotopic filter and has a spectral transmission curve that mimics the spectral response of the human eye under low-light conditions. The component further includes readout electronics for processing the output signal of the silicon photomultiplier.
