OPTICAL ARTICLE HAVING ANTIREFLECTION LAYER

摘要

PURPOSE: To obtain an optical article high in productivity and able to be subjected to antireflection work and having an antireflection film showing high antireflection property in a wide wavelength band. CONSTITUTION: The optical article has an antireflection layer having the 1st layer of a higher reflective index than that of the optical article and the 2nd layer consisting of an amorphous fluorine-containing polymer on the 1st layer on at least one surface thereof, and 0.3×λc < (the 1st layer optical film thickness n1 d1 ) <0.4×λc [λc is designed wavelength], and 0.18×λc < (the 2nd layer optical film thickness n2 d2 ) <0.26×λc .
