New High Power Free Space Isolator

An optical isolator, or optical diode, is an optical component which allows the transmission of light in only one direction. It is typically used to prevent unwanted feedback into an optical oscillator, such as a laser cavity.
The operation of the devices depends on the Faraday effect (magneto-optic effect) in a Garnet Crystal and crossed polarizers. Read more »

Installation and ramp up of Molded Glass lens Production line finished in 2020.
