Abstract
A lens includes a lens tube and the optical element mounted in the lens tube. The lens tube has a top surface, and a conductive layer is disposed on a surface that is of the optical element and that faces a side on which the top surface is located. The lens further includes antistatic structure disposed on the top surface, and an electrostatic conducting wire disposed in a tube wall or on an inner surface or an outer surface of the lens tube. One end of the electrostatic conducting wire is electrically coupled to the antistatic structure, and the other end is grounded.
