The Special Applications And Advantages of MPR122 360 Prism

MPR122 360-Degree Prism, specifically designed for efficient and precise measurements with total stations. It eliminates the limitation of traditional prisms requiring direct alignment with the instrument for measurement.

At its core is a spherical assembly formed by multiple precision optical prism units arranged in a ring configuration. This structure enables effective reflection of total station signals from any horizontal angle, achieving 360-degree omnidirectional measurement.

This feature makes it particularly suitable for the following scenarios:

· Tunnel, mine, and underground surveying: In confined, line-of-sight-restricted environments, instruments no longer need to repeatedly locate the prism's front face, significantly boosting efficiency.

· Automated deformation monitoring: When integrated into automated systems with surveying robots (automated total stations) for monitoring deformations in excavation pits, dams, and bridges, the prism remains fixed while the instrument automatically searches for and measures it.

· Dynamic or hard-to-reach target measurement: In scenarios like ship positioning or large component installation (e.g., caissons), where targets may rotate or are difficult to manually align continuously, the 360-degree prism ensures uninterrupted signal detection.

Compared to standard prisms, the MPR122 360-degree prism offers:

· Comprehensive efficiency gains: Eliminates the need for repeated prism orientation adjustments during measurement, making it ideal for single-person or automated surveying.

· Engineering-grade accuracy: Achieves planar positioning accuracy better than 1 millimeter within 60 meters, meeting most precision engineering measurement requirements.

· Rugged durability: Constructed with premium optical glass and multi-layer protective coatings (copper coating, protective lacquer, anti-reflective coating, etc.), it resists dust and water ingress, withstanding harsh field conditions and chemical corrosion.

In summary, the Leica MPR122 360-degree prism is a professional tool designed to enhance measurement efficiency and automation in complex environments. Its unique omnidirectional reflectivity excels in applications such as tunnels, mines, and automated monitoring, with its high precision and durability stemming from rigorous manufacturing processes.
