The Trimble Small Monitoring Prism is a compact, high‑quality reflective prism designed for use with optical total stations and surveying instruments. It is primarily used as a monitoring target for geospatial measurements, structural deformation tracking, and construction control points. With a small footprint and precision optical design, this prism supports accurate tracking of reference points over time in civil engineering, tunneling, slope monitoring, and infrastructure inspection projects.
Made for both vertical and horizontal mounting, the Trimble Small Monitoring Prism delivers consistent reflective performance. Its optical properties and calibrated prism constant ensure compatibility with Trimble and other total stations when properly configured.
