In the field of professional surveying, accuracy and reliability are the cornerstones of successful projects—whether it’s land mapping, construction layout, rail monitoring, or settlement detection. A high-quality surveying prism is indispensable for achieving precise measurements, as it serves as the critical link between surveying instruments and target points. The GPH1-P High Precision Prism stands out as a top-tier solution, engineered to meet the most demanding accuracy requirements and redefine performance standards for surveying professionals worldwide.
Accuracy is non-negotiable in surveying, and the GPH1-P High Precision Prism excels in this critical area. Boasting an exceptional centering accuracy of ±0.3 mm, this surveying prism ensures that even the most precise measurement demands are met with ease. Its prism diopter is slightly tilted to prevent any EDM (Electronic Distance Measurement) reflection from the front surface—a distinct design feature that effectively eliminates interference and further enhances measurement accuracy.
Crafted with high-quality optical glass and advanced coating technology, the GPH1-P surveying prism delivers superior reflectivity. The prism features a special anti-reflective coating on the front surface and a copper coating on the reverse side, which not only boosts reflectivity but also reduces signal loss by up to 30% compared to uncoated prisms. This ensures that laser beams from total stations are reflected back with maximum intensity, even over long distances, enabling reliable measurements up to 3,500 meters (11,500 ft). With a beam deviation of just 2 arcseconds, the GPH1-P guarantees consistent, precise results that you can depend on for critical surveying tasks.
Surveying professionals often work in challenging outdoor environments, from extreme temperatures to rugged terrain. The GPH1-P High Precision Prism is built to withstand these harsh conditions, thanks to its durable one-piece metal holder and rugged construction. The robust metal frame protects the optical glass from impact, scratches, and wear, ensuring long-term performance even in the most demanding field settings.
The copper coating on the prism not only enhances reflectivity but also provides excellent corrosion resistance, making the GPH1-P surveying prism suitable for use in humid, coastal, or industrial environments. Its compact and lightweight design (dimensions: 118 × 135 × 51 mm) makes it easy to carry and install on surveying poles, reducing operator fatigue during long workdays. Whether you’re working in rain, dust, or extreme temperatures, the GPH1-P remains stable and reliable, delivering consistent performance day after day.
The GPH1-P High Precision Prism is designed for seamless compatibility with most professional total stations, including Leica models—a key advantage for surveying teams that rely on high-end equipment. It features a 12 mm (Leica-compatible) spigot mount, allowing for quick and secure attachment to surveying poles without the need for additional adapters. The prism constant is set to +0.00 mm (Leica constant), ensuring easy integration with Leica total stations—simply set the prism constant on your instrument to 0.0 mm, and you’re ready to start measuring.
With a height offset of 86.0 mm, the GPH1-P surveying prism is perfectly aligned with industry standards, ensuring compatibility with a wide range of surveying workflows and equipment setups. This seamless compatibility eliminates the need for complicated adjustments, saving valuable time on the job site and reducing the risk of errors caused by mismatched equipment.
As a versatile surveying prism, the GPH1-P is suitable for a wide range of professional applications, making it a valuable tool for surveyors, engineers, and construction professionals. It excels in rail monitoring, where precise line and level correlation surveys are required to ensure the safety and accuracy of rail infrastructure projects. In settlement monitoring, the GPH1-P’s high accuracy enables surveyors to detect even the smallest horizontal and vertical movements of structures, providing critical data for risk assessment and project planning.
The GPH1-P surveying prism is also ideal for displacement monitoring, helping to detect land subsidence, landslide movements, and other geological changes with millimeter-level accuracy. Additionally, it is widely used in topographic surveying, construction layout, boundary mapping, and tunnel construction—any application where precise distance and angle measurements are essential. Its long working range and high accuracy make it the perfect choice for both long-distance and detailed surveying tasks.
In a market flooded with ordinary surveying prisms, the GPH1-P stands out for its uncompromising quality, exceptional accuracy, and user-friendly design. Unlike low-cost prisms that sacrifice precision for affordability, the GPH1-P delivers premium performance at a competitive price, making it a cost-effective choice for professional teams. Its advanced features—including the tilted diopter design, high-quality coatings, and robust construction—ensure that it outperforms other surveying prisms in every key metric.
For professional surveying teams that demand accuracy, reliability, and durability, the GPH1-P High Precision Prism is the ultimate choice. As a top-tier surveying prism, it combines advanced optical technology, robust construction, and seamless compatibility to deliver consistent, precise results in even the most challenging environments. Whether you’re working on a large-scale infrastructure project or a detailed topographic survey, the GPH1-P ensures that every measurement is accurate, efficient, and trustworthy.
