Title: Mitsumasa Saito: Innovator in Ultraviolet Ray Shielding Technologies
Introduction
Mitsumasa Saito is a notable inventor based in Narashino, Japan. He has made significant contributions to the field of ultraviolet ray shielding technologies, holding a total of 2 patents. His work focuses on developing materials that effectively shield against harmful ultraviolet rays while allowing visible light to pass through.
Latest Patents
Saito's latest patents include an ultraviolet ray-shielding agent and tube. The ultraviolet ray-shielding agent is designed to selectively shield ultraviolet rays while permitting the transmission of visible rays. It consists of a visible ray-transmitting binder combined with extremely fine zinc oxide particles, which have an average size of 0.1 µm or less. The mixing ratio of the zinc oxide particles to the binder ranges from 1/10 to 10/1. Additionally, he developed an ultraviolet ray-shielding tube for visible ray-irradiation luminescent lamps. This tube features a transparent substrate for sealing a light emission source and a coating made from the aforementioned ultraviolet ray-shielding agent. Another patent involves an ultraviolet-suppressed light source, which includes a coating agent that forms a film of fine powder made from zinc oxide and titanium oxide on the outer surface of a light source. This film acts as an absorbent for ultraviolet radiation emitted from the light source.
