Abstract
An electrostatic discharge apparatus and method for a lens of a hand-held imaging device are provided according to the invention. The electrostatic discharge apparatus includes a main body and an optical lens mounted on the main body. A transparent conductive coating is formed on the optical lens. The device further includes a conductive pad formed on the main body. The conductive pad is in electrical contact with the transparent conductive coating. The conductive pad is located on the main body at a region contacted by a user during use of the hand-held imaging device.
