Abstract:
Proposed is a light sensor (1), comprising at least one wavelength selective photo-detector (10), a lens (20) and an aperture (30).The wavelength selective photo-detector allows detecting light within a predefined wavelength range falling on the sensor. The lens project light on the photo-detector and the aperture defines a field of view of the light sensor. The photo-detector (10), the lens (20), and the aperture (30) are arranged in a telecentric configuration. Advantageously, this allows light to impinge on the wavelength selective photo-detector within a predefined range of angles irrespective of the direction of the light incident on the aperture, thus removing the angle dependent response of the wavelength selective photo-detector.

Thus, the area of a section where the cathode (20) is near the anode (22) is large, so that photoelectrons emitted from the cathode (20) by incidence of ultraviolet rays is propagated through the vacuum and are favorably trapped collected by the anode (22).
