Aperture Manual Rotation Stages

Aperture rotation stages have a center aperture to allow access to the rotation axis for the rotation of elements like polarization optics.  They are designed to provide full 360-degree coarse as well as fine angular travel over a single rotational degree of freedom, most commonly yaw.  The axis of rotation is orthogonal to the mounting platform, unlike goniometers which have their rotation axis parallel to the mounting platform.  These rotation stages are frequently used in applications such as spectrometry, polarimetry, or wherever exact rotational position is required.  Industries that utilize linear stages include research, bio-medical, life sciences, astronomy, metrology, semiconductor, and more.  OptoSigma offers the single largest selection of rotational translation stages to meet virtually any application.  For example,  we have the most bearing options of any manufacturer, including  EXC™ precision bearing, crossed-roller bearing, lapped bearing.   If one of our many catalog stages does not meet your requirements, send us a request for a custom stage.  OptoSigma is, after all, the industry leader in translation stages.
