Compact & Portable: This total station reflective sphere ball prism is engineered for field efficiency — measuring just 30mm in ball diameter and 35mm in magnetic base diameter, it slips easily into tool belts or survey kits without adding bulk; its lightweight aluminum alloy housing and integrated carry bag make it ideal for daily site transitions across rail, tunnel, and construction environments.
Precision Optical Performance: Featuring a prism with 17.8mm diameter and optimized spherical geometry, this prism delivers consistent signal return and minimal phase error across long-range total station measurements; the optical clarity and precise angular alignment support sub-millimeter accuracy required in high-speed rail alignment and structural deformation monitoring.
Strong Magnetic Mounting: Equipped with a high-strength magnet embedded in the aluminum base, this ball prism securely attaches to steel bridges, rail tracks, I-beams, and — eliminating clamps or adhesives while maintaining stable positioning even on vertical or overhead ferrous surfaces during mic survey conditions.
Versatile Surface Compatibility: Unlike standard magnetic prisms, this model includes a centered through-hole in the magnetic base, enabling secure fastening via bolt or anchor to non-magnetic substrates including concrete walls, wooden stakes, and asphalt markers — expanding usability across mixed-material job sites without accessory dependency.
Universal Adjustment Design: The prism head rotates freely on a 360° horizontal plane and tilts ±15° vertically via a precision ball-and-socket joint, allowing rapid realignment to the total station line-of-sight without readjusting the base; all major total stations including SPS, , and GPT series.
