Abstract
An infrared imaging lens system comprises, in order from an object side, a first lens formed of silicon whose minimum transmittance of infrared rays with a wavelength of 8 μm to 13 μm is at least 40% for a thickness of 1 mm, and a second lens formed of chalcogenide glass. The silicon whose minimum transmittance of infrared rays with a wavelength of 8 μm to 13 μm is at least 40% for a thickness of 1 mm can be obtained at low cost for example by controlling the oxygen concentration in CZ method.
