Micro Prism with Magnetic Base, Copper Coating, 38.1mm diameter

Mountlaser MP108 Micro Prism with Magnetic Base | High-Precision Monitoring

Maximise your surveying accuracy with the Mountlaser MP108 Micro Prism. Designed for high-stakes structural monitoring and industrial alignment, this 1.5-inch spherical micro prism is the professional's choice for measuring in tight spaces and on metallic surfaces.

Whether you are tracking bridge deformation or aligning heavy machinery, the MP108 provides a stable, high-precision point that eliminates the need for bulky tripods or poles.

Key Features & Benefits

• Powerful Magnetic Mounting: The integrated heavy-duty magnetic base allows for instant, secure attachment to steel beams, plates, and industrial equipment. Perfect for long-term monitoring or rapid-setup machine control.
• Precision Spherical Design: Encased in a 38.1mm (1.5-inch) stainless steel sphere, the prism can be rotated 360° within its base. This ensures the center point remains consistent ($\pm 0.2\text{mm}$ rotary accuracy), allowing for measurements from any angle without losing precision.
• Superior Accuracy: Featuring a 3-arcsecond prism accuracy and a measuring range of up to 1,000 meters, the MP108 delivers the reliable data required for sensitive engineering projects.
• Durable Construction: Built with high-grade stainless steel, this micro prism is corrosion-resistant and engineered to withstand harsh outdoor environments and industrial job sites.
• Universal Compatibility: With a +14.4mm constant (GeoMax standard), it integrates seamlessly with most total stations and automated monitoring systems.

Why Choose the MP108?

The Mountlaser MP108 is more than just a prism—it’s a solution for environments where every millimeter counts. The combination of a black contrast ring for rapid target acquisition and a rugged magnetic base makes it one of the most versatile monitoring tools in the industry.
