OTI Precision Turntable

The rotary turntable incorporates a HEIDENHAIN ROD 800 rotary encoder whose cumulative error is within ONE SECOND of arc and zero backlash.

Fine rotary adjustment of the table is by a smooth differential micrometer head giving easy one second of arc control.

The 120mm dia. Workpiece table sits on a spherical seat whose tilt is controlled by two smaller micrometer heads. In this way, surfaces being inspected are set parallel to the axis of rotation of the table thus eliminating "cosine" errors.

The photograph shows the table working in conjunction with an O.T.I. AC 20 series autocollimator and stand SR1. This very cost-effective combination, affording precise measurement accuracy, also eliminated the danger of damaging delicate optical surfaces.

The rotary table is supplied with a manual illustrating a thorough analysis of the alignment criteria of Autocollimator relative to the Table, to ensure optimum results.
One-second accuracy can be achieved using unskilled operators.
