摘要
Provided are a lens apparatus and a machine vision system including the lens apparatus. The lens apparatus includes: a first lens group and a second lens group which are designed to use a wavelength of light of a first single color as a reference wavelength and disposed on opposite sides of an aperture; and a converter lens group which is disposed at an object side of the first lens group, wherein the converter lens group performs selectively at least one of a first conversion for converting a magnification, and a second conversion for converting the reference wavelength.
