To afford a more economical upgrade for our current customers, the Zoom 125C Optical System is compatible with all current Thales Optem Zoom 70XL Optical System. The accessories are incorporated above the zoom core, including TV Tubes, Reticle Projectors and Bayonet Adapters. However, due to the special optical design of the Zoom 125C, some accessories integrated below the zoom, such as Auxiliary Lenses and Objectives, are specific to the Zoom 125C.

Every functional Zoom 125C system requires an Upper Module, a Function Module, and a TV Tube to locate the camera at the proper image distance.
