The L-Bar Micro Prism is a compact monitoring target featuring a 12.7mm optical glass prism with a silver anti-reflection coating. Its discreet design makes it particularly suitable for indoor monitoring applications where a low-visibility installation is preferred.
Mounted on a black-anodised aluminium L-bracket with 25mm arms and a single fixing hole, the prism provides a practical solution for establishing monitoring points on suitable structural surfaces. With separate prism offsets for Leica and Topcon, Trimble and compatible instruments, it can be incorporated into a range of surveying and structural monitoring systems.
