    magnetorheological finishing
    Magnetorheological finishing (MRF) is a precision optics polishing technique used for shaping and finishing optical surfaces to achieve extremely high levels of smoothness and accuracy. It is commonly applied to lenses, mirrors, prisms, and other optical components in various industries, including astronomy, microscopy, and laser systems. The process involves using a magnetorheological fluid—a liquid containing ferrous (iron) particles—and a magnetic field to perform the...
    metrology
    Metrology is the science and practice of measurement. It encompasses the theoretical and practical aspects of measurement, including the development of measurement standards, techniques, and instruments, as well as the application of measurement principles in various fields. The primary objectives of metrology are to ensure accuracy, reliability, and consistency in measurements and to establish traceability to recognized standards. Metrology plays a crucial role in science, industry,...
