Abstract:
A lens unit includes: an imaging optical system; and a lens barrel holding the imaging optical system. The imaging optical system includes, in order from an object side: a first lens having a positive refractive power; a second lens including at least one surface having an aspherical shape; and a third lens having a negative refractive power, at least one surface having an aspherical shape, and an inflection point other than an intersection with an optical axis.

Claim (Index 11):
A lens unit comprising:\n an imaging optical system; and a lens barrel holding the imaging optical system, wherein the imaging optical system comprises, in order from an object side:\n a first lens having positive refractive power; \n a second lens having an aspherical surface; and \n a third lens having:\n negative refractive power; \n an aspherical surface; and \n an inflection point other than an intersection with an optical axis, \n \n wherein the imaging optical system satisfies conditional expressions (1) to (3):\n f/TL> 0.92\u2003\u2003(1) \n 0.10> f/f 2>\u22120.17\u2003\u2003(2) \n 0.60> d 2/ f> 0.22\u2003\u2003(3), \n wherein \n f is a focal length of an entirety of the imaging optical system, \n TL is a distance from a lens surface closest to the object side to an image side focal point on the optical axis, \n d2 is an axial air space between the first lens and the second lens, and \n f2 is a focal length of the second lens.
