The GPH1P Accurate Reflective Prism is a premium surveying accessory developed for professionals who demand consistent accuracy, durability, and dependable signal performance in every measurement task. Designed for modern surveying workflows, this prism assembly combines advanced optical technology with robust mechanical construction to deliver reliable results in even the most challenging field environments. As a professional-grade solution, the GPH1P High Precision Circular Prism with Holder is ideal for control surveys, construction layout, monitoring, and engineering applications where precision is non-negotiable.
At its core, the GPH1P Accurate Reflective Prism features a high-quality 64 mm circular prism engineered for excellent reflectivity and minimal measurement deviation. Surveyors can select accuracy levels of 2 seconds or 3–4 seconds, allowing the prism to be precisely matched to project requirements. This flexibility ensures that the GPH1P High Precision Circular Prism with Holder performs equally well in high-precision control work and demanding everyday surveying tasks.
The prism is securely mounted in a sturdy metal holder that provides superior stability compared to plastic alternatives. This metal housing protects the optical element from impact, vibration, and environmental stress, significantly extending service life. Thanks to this design, the GPH1P Accurate Reflective Prism maintains alignment and optical integrity even under intensive daily use.
Another key advantage is the incorporation of a constant 0 mm offset. This design simplifies field setup and eliminates the need for offset corrections during measurement, reducing the risk of human error. With the GPH1P High Precision Circular Prism with Holder, surveyors can rely on a consistent reference point, improving workflow efficiency and data reliability.
To further enhance performance, the GPH1P Accurate Reflective Prism is equipped with a double copper-coated prism with blue coating. This advanced coating technology significantly improves signal return, especially over long distances or in low-visibility conditions. The result is faster target acquisition, more stable tracking, and higher confidence in measurement accuracy when using total stations.
Portability and protection are also carefully considered. Each GPH1P High Precision Circular Prism with Holder is supplied with a dedicated protective carry case. This case safeguards the prism during transport and storage, protecting it from dust, moisture, and accidental damage while ensuring it is always ready for field deployment.

Key Features of the GPH1P Accurate Reflective Prism
Constant 0 mm Offset for Simplified Setup
The GPH1P Accurate Reflective Prism incorporates a true 0 mm offset to streamline field operations. This allows surveyors to set up quickly without additional calculations or corrections. Consistent referencing improves efficiency and reduces the likelihood of measurement errors.
Double Copper-Coated Prism with Blue Coating
Advanced double copper coating with a blue finish enhances reflectivity and signal strength. This improves measurement precision, especially over long distances or in complex environments. The GPH1P High Precision Circular Prism with Holder delivers stable, reliable signal return for professional surveying tasks.
Protective Carry Case Included
A durable carry case is included to protect the prism during transportation and storage. This helps preserve optical accuracy and mechanical integrity over time. With proper protection, the GPH1P Accurate Reflective Prism remains dependable throughout its service life.
