High Precision Vertical Lift Stage


The AT10-120 Motorized Vertical Stage from Optimal Engineering Systems, Inc. (OES) is a high resolution, low profile, high load vertical lift stage that can be easily integrated into almost any application.

The large 8.7 by 5.5 in. drilled and tapped platform has a vertical travel of 4.3 In.

The twin lead (right and left hand thread) precision ground screw and six guide rails provides smooth, flat (parallel to mounting surface), vertical motion, and high resolution to 5 µ (non-microstepping) and 0.50 µ (10 Microstep Driver), and repeatability is 10 µ at travel speeds of 5 mm/sec.

Applications for the AT10-120 vertical lift stage include: Testing, inspection, assembly, sampling, laser drilling and machining in a broad range of industrial, medical, semiconductor, and research facilities.

The AT10-120 low profile (3.54 in.) vertical stage is constructed of black-anodized aluminum alloy and weighs just 13.23 lb. The powerful 2-phase NEMA 23 Stepper and inclined plane and scissor lift concept offers higher load capacity to 33 lb. compared to vertically mounted stages, and without the concern for cantilevered effects (loss of parallelism), additionally, the moving platform has access from all four sides, and the base plate has easy to access holes for mounting.
