Title:
ACTINOMETER
Document Type and Number:
WIPO Patent Application WO/2023/218542
Kind Code:
A1
Abstract:
Provided is an actinometer with which it is possible to accurately measure an amount of solar radiation in a continuously stable manner while suppressing the generation of dew or frost using a simple configuration, even while an external environment is changing. This actinometer 10 comprises: a thermoconductive casing 101 having an opening section 10121; an optically transparent dome 201 provided to the opening section 10121; a sensor unit 401 provided to an internal space formed by the casing 101 and the dome 201, the sensor unit 401 measuring the intensity of sunlight that is incident through the dome 201; and a heat-generating element 501 located on the opposite side from the opening 10121 with the internal space therebetween, the heat-generating element 501 being provided so as to be capable of conducting heat to one section of the casing 101.
