Abstract: An optical inspection device includes: a barrel; a first light source unit at a first side of the barrel and configured to irradiate light of a first wavelength range through a first light path; a second light source unit at a second side of the barrel, the second side being different from the first side, and configured to irradiate light of a second wavelength range that is different from the first wavelength range through a second light path; and a camera. At least a portion of the first light path is different from the second light path.
