The complete Zoom 6000 Lens System requires an Adapter Tube component. When combined with the C-mount coupler, the adapter tube places the camera sensor at the optical image plane of the zoom system. Adapter tubes are available in magnifications range from 0.5X to 5.0X. To provide flexibility to the overall system length, adapter tubes are available in compressed "mini" and “short” versions or choose a right angle adapter and mount to vary the orientation and optical path of the system.
