Abstract: The infrared camera apparatus incorporates an infrared lens system that retains high resolution power and yet is successfully reduced in a required volume of infrared lens material that is hard to obtain and expensive, so as to attain a compact and cost-reduced infrared camera apparatus incorporating such an infrared lens system. The infrared lens system has at least a single Fresnel lens piece that has at least one of its opposite sides formed in a Fresnel surface. The Fresnel lens piece is made of a lens material of which transmissivity to light waves of one or more monowavelength(s) within an available wavelength range from 3000 nm to 14000 nm is 35% or higher when it takes a shape of 4-mm thickness uncoated parallel flat plate.

Abstract: An object of the present invention is to provide an optical system for an infrared ray which can provide a bright image, and can be applied to fixed focal length lenses among wide-angle to medium-telephoto. To achieve the object, the optical system for an infrared ray is constituted by a first lens having negative refractive power and a second lens having positive refractive power, these are arranged sequentially from an object side, wherein both the first lens and the second lens are made of an infrared transmitting material that transmits a light beam in an infrared wavelength range of 3 micron-meters or more to 14 micron-meters or less, and at least one of the lenses is made of an infrared transmitting material excluding germanium.
