Edmund Industrial Optics announced it has launched a new magnetorheological finishing (MRF) optical polishing capability at its corporate headquarters, in Barrington, N.J. MRF is a polishing technology in which a "smart fluid" changes viscosity when exposed to a magnetic field. The company said the technology will enable it to perform high-precision raster polishing of a variety of prisms and that it is ideal for polishing visible and near-infrared optics. Edmund also announced it has released its January 2004 catalog of more than 10,000 optic and optical component products, including multi-element lenses, lens coatings, imaging systems and opto-mechanical equipment for applications including semiconductor manufacturing, industrial metrology, and medical instrumentation.

Kopin said its system is the highest-resolution viewfinder ever used in a DSC. The DiMAGE A2 is being sold in Asia and is expected to be available in the US by the end of this month.

Glossary
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,...
