Mini Prism for Total Station 30mm Offset K9 Glass Accurate Distance Measurement for Tunnel Surveying

Mini prism for total station use, featuring K9 optical glass and a fixed 30 mm offset. Designed for tunnel and mine detection and general surveying instruments, this compact prism delivers reliable target in confined and challenging environments. Key benefits Accurate alignment and distance measurement: 30 mm offset provides a consistent reference from the prism face to the instrument optical axis, simplifying setup and reducing calculation steps. quality optical : K9 glass gives clear, stable reflections for reliable measurement readings with compatible total station systems. Compact and easy to handle: Mini form factor fits tight spaces such as tunnels, shafts, and underground workings, making field work faster and less cumbersome. Broad instrument compatibility: Works with standard total stations and common surveying instruments that accept single prisms with a 30 mm offset. Practical field use: Lightweight and portable for quick deployment and frequent repositioning during surveying campaigns. Product attributes Function: Single mini prism for use with total stations and other surveying instruments for distance and angle measurements and alignment tasks. Optical material: K9 optical glass for consistent reflection quality. Offset: 30 mm fixed offset to align with instrument reference geometry. Size: Miniature prism design for confinedspace applications and easier transport. Performance: Stable target suitable for tunnel, mine, and general surveying operations. Typical use scenarios Tunnel alignment and monitoring: Place the mini prism along tunnel axes or at monitoring points to verify alignment, control excavation direction, and check clearance in confined sections. Underground mine surveying: Use the compact prism for rapid stationing in drifts and stopes where space is limited and frequent repositioning is required. Confinedspace construction surveying: Deploy during shaft sinking or internal structure layout when a small, reliable target is needed for total station measurements. What makes this prism stand out Purposebuilt mini form factor for restricted environments where standard prisms are impractical. K9 optical glass delivers dependable returns without complicating instrument setup. Fixed 30 mm offset provides predictable geometry for straightforward data collection and processing. Compatibility note Designed for use with total stations and surveying instruments that accept single prisms and a 30 mm offset. Verify instrument settings to ensure correct offset compensation during measurement. This mini prism is a practical tool for surveyors working in tunnels, mines, and other confined or frequentrepositioning environments where compact size and reliable performance matter.
