| titleOfInvention | Lens, far-infrared lens system, imaging optical device and digital equipment |
| abstract | A lens that is inexpensive and easy to process, has excellent far-infrared transmittance, and has high aberration correction capability, and a high-performance and inexpensive far-infrared lens system that is well-corrected for aberrations with its two-lens configuration, including the same An imaging optical device and a digital device are provided. A far-infrared lens system LN is a lens system used in a far-infrared band, and is composed of two lenses, a first lens L1 and a second lens L2, in order from the object side. Each of the lenses L1 and L2 has a lens core made of an inorganic material having a refractive index greater than 2.0 and not more than 3.9 at a wavelength of 10 μm, and a coating layer made of a resin material covering the lens core. At least one surface constituting the lens surface of the lens core is a spherical surface, the surface of the coating layer provided on the spherical surface is an aspheric surface, and the thickness of the coating layer is 0.01 mm or more at the thinnest point, The thickest part is 0.7 mm or less.
