More Information
Summary:An ultraviolet sensor includes a silicon photodiode array having a plurality of first pixel regions and a plurality of second pixel regions. A filter film is disposed on each of the first pixel regions so as to cover each first pixel region, except on each second pixel region. The filter film lowers transmittance in a detection target wavelength range in the ultraviolet region. Each of each first pixel region and each second pixel region includes at least one pixel having an avalanche photodiode to operate in Geiger mode, and a quenching resistor connected in series to the avalanche photodiode. Each of the quenching resistors in the plurality of first pixel regions is connected through a first signal line to a first output terminal. Each of the quenching resistors in the plurality of second pixel regions is connected through a second signal line to a second output terminal.
