Features
High Efficiency Performance
The YIG crystal utilized in our Faraday isolators creates a large Verdet constant that ultimately describes the strength of the Faraday effect and provides effective isolation of back-reflected light. Additionally, these isolators have low absorption as a function of the YIG crystal and polarizers, resulting in reliable transmission of light in the forward direction.
Corning Polarcor™ Absorptive Polarizer
The LP Series uses a high efficiency Corning Polarcor™ absorptive polarizer. It offers a 25 W/cm2 CW damage threshold for lower power laser diode applications.
