Ultra-high Precision Coordinate Measuring Machine
The Hexagon Leitz Infinity represents the absolute zenith of ultra-high-precision coordinate metrology, designed for the most demanding applications where measurement uncertainty must be minimized to the nanometre level. It is the instrument of choice for national metrology institutes, premier calibration laboratories, and advanced industries such as optical component manufacturing, high-end semiconductor tooling, and precision gear production, where the limits of dimensional tolerances are constantly being pushed.
The Infinity is the culmination of Leitz's legendary expertise in metrology system design. Every aspect is engineered to eliminate error sources. It is constructed from materials with exceptional long-term stability, such as special granite and ceramics, housed within a highly controlled thermal enclosure. The machine's environment is actively stabilized, with multi-zone temperature control maintaining the air and structure at a uniform 20°C, often within a tolerance of a few hundredths of a degree. This neutralizes the primary enemy of high-accuracy measurement: thermal expansion.
Its motion system is a marvel of precision. It utilizes non-contact, frictionless drives and ultra-stable guideways. The metrology frame is designed to follow the Abbe principle, aligning measurement axes to minimize Abbe offset errors. Laser interferometers, the gold standard for length measurement, are directly integrated into the axis feedback system, providing unparalleled positional accuracy traceable to the international definition of the metre.
The heart of the Infinity is often the Leitz LSP-S series scanning probe, a 3D analog sensor capable of capturing thousands of surface points per second with minimal contact force and exceptional repeatability. This allows for the exhaustive measurement of form, waviness, and roughness on even the most delicate surfaces. The system is governed by the QUINDOS software suite, renowned in high-precision circles for its powerful evaluation algorithms for geometries like gears, turbines, and free-form optics.
The Leitz Infinity is more than a measuring machine; it is a primary standard within a laboratory. It is used to calibrate master artifacts, gauge blocks, and other high-precision tools, establishing traceability down the supply chain. For companies developing next-generation technologies, it provides the confidence that their most critical components are measured with the highest possible fidelity, ensuring performance, reliability, and innovation.
