An infrared transmission optics formed with an anti-reflection pattern is provided. The infrared transmission optics is manufactured in the steps of i) applying a PR layer on the surface of an optics plate, ii) manufacturing an etching barrier pattern of a sinusoidal wave shape on the PR layer, and iii) manufacturing a pattern of a projection form on the plate where the etching barrier pattern is formed, through an etching process.
