Our 1" Double-Threaded Mountable Lens Tubes are similar to standard lens tubes, however the internal thread is double threaded (2 leads). The double thread allows the retaining ring to move twice as far per revolution when compared to a standard thread. These lens tubes are fully compatible with standard lens tubes; standard external and internal threads are located so that interchangeability is possible.
Our Double-Threaded Mountable Lens Tubes also have a lens-locating feature that allows the inserted lens to be concentric within .001" of center.
