Gradient Index Lens – Grin Lens
Gradient Index Lens – Grin Lens is a micro gradient index lens.
It is designed for use in focusing and collimation, e.g. WDM, optical couplers, collimators, optical isolators and demanding telecommunication and date communication applications
A Faraday isolator or optical isolator is an optical component which allows the transmission of polarised light in only one direction. They are typically used to prevent unwanted feedback into an optical oscillator (A laser cavity is a good example.) The operation of the device depends on the Faraday effect which is used in the main component, the Faraday rotator.
