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.

Abstract: The invention provides an infrared fixed-focus lens of which component lens pieces are made of germanium characterized by low chromatic dispersion, and have no surface processed to serve as diffraction optics. The infrared fixed-focus lens comprises a first lens piece disposed closer to an object and of negative power, and a second lens piece disposed closer to the image plane and of positive power. Both the first and second lens pieces are made of germanium.

Abstract: A correction lens is used in an optical system in which a light-transmissive cover member having radii of curvature different from each other in a predetermined first direction and a second direction perpendicular to the first direction is disposed on an object side. Radii of curvature of an image-side surface of the correction lens are different in the first direction and the second direction, and satisfy a predetermined condition.
