Abstract:
A single focal length lens system which, in order from an object side to an image side, includes a first unit, an aperture diaphragm, and a second unit is provided. The second unit includes a cemented lens having positive optical power, and a joint surface of the cemented lens is an aspheric surface. The cemented lens satisfies a condition: |dn/dt1| MAX ≤2.67×10 −5  (|dn/dt1| MAX : A Maximum Value of Absolute Values of Relative Refractive Index temperature coefficients in an atmosphere at 0 to 20° C. with respect to light having a wavelength range of 580 to 640 nm, which is calculated for each of lens elements constituting the cemented lens).

Claim (Index 11):
A lens system as claimed in  claim 6 , wherein the following condition (3) is satisfied:\n 2.0< f CEM /f< 4.0\u2003\u2003(3) where f CEM  is a focal length at d-line of the cemented lens, and f is a focal length at d-line of the lens system.
