SECO Circulas Prism

The SECO Circular Prism is a precision reflective target designed for use with optical total stations in surveying, construction, and geotechnical monitoring applications. Its circular design offers uniform reflection from multiple angles, which improves target visibility and measurement reliability — especially in dynamic field environments where maintaining direct instrument alignment can be challenging.

This prism is engineered for durability and consistent optical performance. The reflective element is typically encased in a robust canister to protect against dust and moisture, ensuring dependable measurements even in outdoor conditions. SECO prisms are compatible with a broad range of total station systems and commonly used in tasks such as structural deformation monitoring, site control, and construction layout.

The SECO Circular Prism provides a reliable, accurate, and versatile surveying reflector solution — empowering surveyors and engineers to achieve high‑quality optical measurements across a range of civil, construction, and geotechnical projects.
