Double-Beam Plane-Mirror Interferometer - SP-DS

Double Beam Plane-Mirror Interferometer - SP-DS

Double-beam plane-mirror interferometers of the SP-DS series allow a wide variety of applications as OEM measuring systems or standalone units. Two parallel measuring beams are used to acquire two length values independently of each other and with maximum resolution and precision. Difference values or angle values may be calculated from this and the factory-calibrated beam spacing. The single-beam measuring principle applied to every measuring beam allows measuring setups in compliance with the Abbé princple which avoids first-order measurement errors.
