Manual Rotary Stages

The DT series of rotary stages provide precision, manual rotational adjustment over 360°. With an optional motor drive, these become the DTM series (see the motorised positioning section). The DV rotary adjustment stages trade a slightly lower precision for a reduced cost.

DV 65 Rotary Adjustment Stage

The DV 65 rotary adjustment stage allows an unlimited rotation, that is not entirely backlash-free. The 37mm aperture allows the user to hold large optics using special adapters. Other adapter plates are available for mounting translation or measuring stages. The worm gear is not preloaded and its drive shaft can be uncoupled for fast and rough adjustment. The DV 65 is compatible with the SYS 65 rail system.
