Description
McBain Instruments Precision XY Stage Granite Base 2.5in Travel Micrometer Mount
This McBain Instruments precision XY stage is mounted on a 180 lb solid granite base designed to provide maximum vibration isolation and dimensional stability for sensitive optical and measurement work. The stage platform is machined aluminum with a threaded hole grid for fixture mounting, and each axis is adjusted via micrometer mounts for fine, repeatable positioning. The assembly includes a vertical post for additional instrument mounting or beam delivery.

Applications
Precision XY stages on granite bases are standard equipment in optical and photonics labs, metrology setups, semiconductor inspection, and precision measurement environments where vibration, thermal drift, and mechanical creep must be minimized. The heavy granite base acts as a passive vibration-damping platform, isolating sensitive instruments from floor-transmitted vibration — an approach used in interferometry, laser alignment, microscopy, and surface profiling. The micrometer-driven axes allow sub-millimeter positioning for tasks such as aligning optical fibers, positioning test samples under a microscope or sensor, or scanning a workpiece in a repeatable grid pattern. McBain Instruments was a California-based manufacturer of precision positioning equipment serving the optics, defense, and semiconductor industries, and their granite-base XY stages were common on optical benches and inspection stations from the 1980s onward.
This McBain Instruments Precision XY Stage with Granite Base is new and unused, supplied in a plain brown box rather than retail packaging. The stage, granite base, vertical post, and micrometer mounts are all present as shown in the photos. There is no evidence of prior use or wear. Please note that the item comes only with the components shown in the photos — no additional accessories are included. Please view our photo set and contact us if you have any questions.
