Abstract: Provided are a reel-to-reel inspection apparatus and method. The reel-to-reel inspection apparatus includes: an unwinding unit configured to unwind a roll-shaped object; a first inspection unit configured to photograph a surface of the object discharged from the unwinding unit; a second inspection unit configured to photograph another surface of the object which has passed through the first inspection unit; a marking unit configured to indicate a mark on the object which has passed through the second inspection unit; and a winding unit configured to wind in a roll shape the object which has passed through the marking unit.

Abstract: 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.
