    The DAG20-120-01 and DAG20-120-04 are high resolution, compact, low profile elevator stages. They feature high stability 4.7 x 4.7 in. (120 x 120 mm) tables and 0.79 in. (20 mm) of vertical travel. High precision ball bearing profile rails assure very high parallelism and smooth motion throughout the raising and lowering of the table.  These Z-axis stages are ideal for microscopy, inspection, metrology, positioning, photonics, sampling, and laser drilling and machining.

     

    The black anodized aluminum alloy stages are driven by Two-Phase Stepper Motors, feature 0.00008 in. (2 ?m) positioning accuracy, and resolutions of 0.000001 in. (0.03 ?m) (with a 10 Micro-steps per step motor driver in use). The DAG20-120-01 has a knob for manual adjustment, while the DAG20-120-04 has a Quadrature Incremental Optical Encoder for position verification.

     

    The table of each stage has a precise pattern of threaded holes for fixtures or tooling, and holes in the base allow for easy integration into a new or existing application.
