The portable FiBOTM 300 true phase shifting Michelson interferometers from PROMET International, Inc. (Shoreview, MN) are designed for 3D surface mapping and visual defect evaluation capability. Features include calibrated objectives ranging from 1.8× to 20× of actual optical magnification; photonic crystal fiber; micro-lens arrays; 3D image viewer; USB 2.0 interface; and calibration targets for 2D, 3D, phase shift, and apex offset with optional NIST traceability. Test parameters may be modified for surface-defect detection and mapping zones.
