The Agilent/Keysight 10705A is a compact single-axis linear interferometer engineered for precision metrology in space-constrained and low-mass applications. Its single-beam design superimposes outgoing and returning beams, simplifying optical paths for confined measurement setups. The 10705A delivers non-contact position measurement with fundamental optical resolution of λ/2 (316.5 nm, 12.5 µin) and achieves system resolution down to λ/512 (1.2 nm, 0.047 µin) using 256× electronic resolution extension.
