Title:
STRUCTURE REFLECTING ONE OR BOTH OF NEAR ULTRAVIOLET RAYS AND NEAR INFRARED RAYS
Document Type and Number:
Japanese Patent JP3158830
Kind Code:
B2
Abstract:
PURPOSE: To obtain a structure capable of being easily spun and reflecting near ultraviolet rays and reducing a temp. rise due to near infrared rays.
CONSTITUTION: An alternately laminated structure is formed from a substance layer 101 with an optical refractive index na and thickness da reflecting near infrared rays and a substance layer 102 with an optical refractive index nb and thickness db so as to form the relation of 0.6μm≥2(nada+nbdb)≤1.6μm (1.0≤na≤1.8, 1.3≤nb≤1.8, 1.25≤nb/na≤1.8) and the relation defined by the optical thickness sum λ1=2(nada+nbdb) of the substance layers 101, 102.
