Evanescent Optics Inc. acquired the assets and employee group of Canadian Instrumentation & Research Ltd. in August 2009 and continues production and development of the suite of fiber optic components and interferometric sensors from our new Burlington location. CIR continues to offer support as needed and partners EOI in R&D activity.
Canadian Instrumentation & Research Ltd. Was incorporated in 1975 as an R&D group contracting in Optics and associated disciplines for Federal Government and commercial organizations
The evanescent wave technology essentially pioneered at Stanford by Professor Shaw et. al. was built on and expanded by the development and patenting of a method for optical contact of polished fibers. This allowed the assembly of couplers without any interleaving layer of index matching adhesive or oil and resulted in the high quality devices currently manufactured. Splice free arrays and interferometers can be fabricated as coupler halves and can be made on a continuous length of fiber.
Development and manufacturing of fiber optic components and fiber optic sensors has been ongoing since the early 1980's, resulting in the range of polarization maintaining and polarization preserving devices listed in the products section.
Custom precision mechanical devices and electronic control systems are also a significant part of company history and continue with the current work of EOI Inc.
