An open linear encoder consists of a measuring scale and a scanning head moving opposite each other, contact-free and without a protective housing. The exposed design enables significantly higher accuracy and resolution than an enclosed encoder, suited for applications demanding maximum precision in a clean environment. Key Advantages • Highest accuracy and resolution in the linear encoder family • Contact-free optical scanning — no mechanical wear • Multiple scale types: glass, glass-ceramic, steel tape • Dedicated vacuum-compatible model available (LIC +V) • Compact, suited for space-constrained instrumentation Main Applications Semiconductor lithography and inspection equipment, metrology labs, high-precision machine tools, and nanopositioning stages.
