An adapter tube is a required component for the complete Zoom or Fixed-Magnification imaging system. When combined with the C-mount coupler, the adapter tube places the camera sensor at the optical image plane of the zoom system. Most adapter tubes contain some kind of focusing action to critically align the sensor with the image plane, thus producing a system that zooms in focus (parfocal zoom).

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.

2X F-mount: Designed for covering large format sensors (up to 30 mm diagonal with Zoom 6000 System). It is configured as an F-mount, but its “T” mount interface permits switching to other common flange formats. A right angle version is available for use with right angle mounts.
