Since the lens is replaced as single unit, repairs are not made to its internal components. Disassembling the lens
will introduce dust that will degrade the picture quality and void the warranty.
The lens consists of five motors, four position sensors, a laser light source and IR light sources. The CCD
assembly is an integral part of the lens assembly.
