摘要：
A pyranometer comprises: a light sensor; a first lens arranged to face a light-receiving surface of the light sensor; and a light-shielding ring arranged between the light sensor and the first lens, the light-shielding ring having a light-transmissive region allowing transmission of light at some angles of incidence in the light passing through the first lens.
