The Leica GFZ3 Diagonal Eyepiece is a precision optical accessory designed for Leica TS Series total stations. Featuring a 90-degree elbow viewing angle, it enables comfortable observation of steep vertical sights and zenith measurements, reducing operator strain during surveying tasks. The GFZ3 eyepiece is ideal for surveyors who frequently work with high-angle targets, towers, structures, and overhead control points.
Surveying projects often require observations at steep angles, making direct viewing through a standard telescope eyepiece difficult and uncomfortable. The Leica GFZ3 90° diagonal eyepiece solves this challenge by redirecting the viewing angle, allowing operators to observe targets near the zenith without awkward body positioning.
Designed for compatibility with Leica TS06, TS09, TS11, TS15, TS16, and most Swiss TPS and TS series instruments, this accessory improves workflow efficiency while maintaining optical clarity and measurement accuracy.
