mid-ir faraday optical isolator model ISO-04-0.05um

Overview

Our Mid-IR Faraday optical isolators act essentially as a uni-directional light valve. It is used to protect a laser source near 2050 nm or 4550 nm from destabilizing feedback or actual damage from back-reflected light.

2050 & 4550 nm Mid-IR center wavelengths
High Verdet constant
Low absorption coefficients
1/2 waveplate option (-W models)

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.
