45° Total Station Reflective Prism for Tunnel Construction Accurate Survey Reflector Durable Design

45degree Total Station Reflective Prism for Tunnel Construction Keep survey measurements accurate in confined and angled spaces with a 45degree reflective prism designed for use with total stations and electronic distance meters. Built for tunnel construction and other environments where direct lineofsight is limited, this plastic survey reflector prism offers reliable returns and simple handling. Key benefits Solves lineofsight challenges: the 45degree orientation lets you capture accurate measurements when the instrument cannot be placed directly inline with the target. Lightweight and easy to carry: plastic housing reduces weight for fast setup and transfers between sites. Durable construction for jobsite use: a practical plastic body protects the optical element while reducing the risk of damage during routine handling. Clear, compatible performance: intended for use with total stations and EDM instruments that accept reflective prisms, providing dependable signal for distance and angle measurements. Fast setup and positioning: compact form factor works well in tight spaces such as tunnels, shafts, and confined worksites. Function and compatibility Function: serves as a reflective target for total station and EDM measurements with a fixed 45degree reflecting face. Compatibility: designed to work with total stations and surveying instruments that support external reflective prisms and 45degree prism measurements. Material: rugged plastic housing around the optical prism for impact resistance and practical field use. Size and handling: compact and lightweight for placement in narrow or hardtoreach locations common on tunnel projects. Typical applications Tunnel alignment and surveying: measure offsets and set out control points when the instrument cannot be positioned on the tunnel centerline. Confined space measurement: use inside shafts, culverts, and manholes where angle adjustments are needed to instrument signals. Underground construction and mining: establish reference points and verify geometry in restrictedaccess areas. Practical advantages Minimizes rework by enabling accurate measurements without complex instrument repositioning. Reduces operator fatigue through easy transport and simple placement. Improves workflow in projects that require frequent measurements in constrained environments. This 45degree reflective prism is a practical accessory for survey teams working in tunnels and other confined sites where accurate angle and distance measurement is required but direct lineofsight placement of the instrument is not possible.
