OMNI Survey 1.5" Prism Ball Reflector Kit The OMNI Survey 1.5" Ball Reflector Kit is a complete monitoring and control solution designed for high-precision total station measurements in challenging environments. Featuring magnetic spherical prisms with durable coatings and flexible mounting options, this kit enables fast setup and reliable targeting for deformation monitoring, structural analysis, and control networks. Each 1.5" reflective sphere incorporates a precision 1" prism housed within a hardened stainless-steel body, delivering consistent accuracy and long-term durability in harsh field conditions. Magnetic bases and multiple mounting accessories allow secure placement on steel structures, anchors, or custom installations. Key Features • Complete kit with (5) 1.5" magnetic ball prisms and mounting accessories • Hardened stainless-steel sphere for durability in long-term monitoring applications • High-precision prism with anti-reflective coating and ~3 arc sec accuracy • Magnetic mounting base with centering pin for quick, repeatable setup on steel surfaces • Copper or silver coated prism options for optimal reflectivity and performance • Multiple mounting solutions including drift nests, anchors, and adapters for flexible deployment • Designed for harsh environments and long-term monitoring projects Ideal For Ideal for structural and deformation monitoring on bridges, tunnels, and buildings, as well as rail, mining, and geotechnical applications. Well suited for establishing semi-permanent or permanent control points in confined or obstructed areas where prism poles are not practical, and for industrial environments requiring repeatable, high-accuracy prism positioning .
