The 360° Prism Topcon Style +28.1 mm is a precision reflective target designed to maximise the performance of Topcon-compatible robotic total stations. With its full 360-degree omnidirectional reflection, this prism eliminates the need for manual alignment and allows total stations to automatically lock and track from any horizontal direction — increasing efficiency and reducing field setup time.

Built for professional use, the prism features a +28.1 mm prism constant, making it ideal for accurate distance and angle measurements within Topcon workflows. Its robust construction ensures reliable operation in demanding environments, while the standard 5/8″ mounting thread allows easy attachment to poles, tribrachs, or adapters used in modern surveying setups.

Key Features:

• Full 360° reflectivity for uninterrupted robotic tracking

• +28.1 mm prism constant for precise measurement compatibility

• Designed for Topcon-style total stations and robotic systems

• Standard 5/8″ mounting thread for versatile installation

• Rugged design built to withstand field conditions

Ideal for surveyors, engineers, and construction professionals, this 360° prism enhances productivity on stakeout, topographic, and layout jobs by enabling faster, more reliable automated surveying operations.
