Features

1/2 Waveplate Option

We offer versions with an added zero order 1/2 wave plate (-W models) at the output stage so that the direction of the output beam polarization can be rotated to a desired direction.

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/cm²CW damage threshold for lower power laser diode applications.
