Product Description
This table was first manufactured by N.E.A.T (New England Affiliated Technologies) which later merged with Dover Instruments. Recently, both companies are now represented by Danaher Precision Systems, making this stage of very recent manufacture. It features both small-angle theta rotation and Z-axis elevation. Z axis control is via a cam following a precision wedge. For this reason the stage must be used in a horizontal configuration.
Table diameter – 200mm
Theta rotary travel – plus / minus 4 degrees
Z-axis travel – approximately 12.5mm
Positional accuracy – 10 microns height, 0.05 degrees theta
Stage base dimensions – 7.874 x 7.874 inches
Minimum table height – 3.465 inches
Z-axis ways – four 25mm diameter non-recirculating bearing columns
Z-axis motor – VEXTA Model PH268M-E1.5B
Z-axis motor equipped with VEXTA Clean Damper Model D6CL-6.3 OY8
Stage serial number – 38231
Pitch and yaw – 15 arc-seconds
Payload – 10 kg
Serial number – 38613

The table is in superb condition and includes two of the four connection cables (one cable for the Z-axis motor, and one cable for each axis limit sensors). The pair of axis cables terminates in a single connector. It does not include the cables for the theta rotation – they will need to be sourced separately.
