INFRARED TRANSMISSION FILM, OPTICAL FILM, ANTIREFLECTION FILM, OPTICAL COMPONENT, OPTICAL SYSTEM AND IMAGING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a new infrared transmission film to be applied to an optical component used in a far infrared wavelength region, the film which is easily formed and has high water resistance, and an optical film, an antireflection film, an optical component and an optical system including the infrared transmission film.;SOLUTION: The infrared transmission film essentially comprises zinc oxide and contains a metal oxide as an additive having an extinction coefficient of 0.4 or less in the whole wavelength region from 8 μm to 14 μm.;SELECTED DRAWING: None;COPYRIGHT: (C)2017,JPO&INPIT
