Compact Precision Vertical Stage, 4.8 mm Travel, DC Servo with Tachometer, 4-40 and 8-32

The VP-5ZA vertical stage is an ultra-low profile, precision vertical stage with minimum incremental motion capability of 60 nm, high-responsiveness and perfectly straight trajectory over 4.8 mm travel. Features include: an innovative inclined-plane design; a cool running, high torque DC motor with a precision preloaded, long-life, ball screw ensuring high speed motion with minimum settling time; a high-resolution linear scale directly attached to the moving rail, eliminating all drive-train induced motion errors; and two pairs of vertically mounted double-row linear ball bearing slides resulting in pure vertical motion. A standard 3-point mounting interface for a wafer chuck is provided as well. Manual vertical adjustments can be made using a flat screw driver for convenience. Typical applications include: semiconductor wafer inspection, photonics test and packaging, micro-assembly, precision metrology, and surface inspection systems. The VP-5ZA is compatible with the VP-25X linear stages and other Newport positioning products. For mounting to optical tables or to the ILS linear stages, use the optional base plate VP-BP.
