Abstract
The invention relates to a photo-detector comprising a light sensitive element () and a wavelength converter () arranged in front of the light sensitive element, the wavelength converter being configured to convert light of a first wavelength into light of a second wavelength and to direct the light of the second wavelength to the light sensitive element. The advantage is that a stable reading across the entire visible spectrum may be provided.
