Abstract
The invention provides an optical component, an infrared camera including the optical component, and a method for manufacturing the optical component. Antireflection materialsA are formed on a chalcogenide glassof which a compositional ratio of germanium and selenium is 60 percent or greater. With respect to the antireflection materialsA, an extinction coefficient to light of 10.5 μm is 0.01 or less, and a refractive index to light having a wavelength of 10.5 μm are greater than 1 and 2.6 or less. The antireflection materialsA are formed on a surface of a chalcogenide glassat an interval of 0.5 μm to 2.0 μm, so as to form an antireflection film. Adhesiveness of the antireflection filmis higher than that In a case where the surface of the chalcogenide glassis evenly coated with the antireflection materialsA.
