Original Abstract Submitted
An optical system includes a first lens L with positive refractive power, a second lens L with negative refractive power, and a third lens L with positive refractive power, placed in this order from an object side to an image side. At least one of the first lens L and the third lens L is made of chalcogenide material, and the second lens L is made of glass material. The following inequality is satisfied: 0.75<Np−Nn, where Np is a refractive index of the lens made of the chalcogenide material at a wavelength of 0.9 μm, and Nn is a refractive index of the second lens at a wavelength of 0.9 μm.
