532nm Dual-Polarization Related Free-Space Isolator

Free-space isolators can be divided into two types: polarization-dependent and polarization-independent. The polarization-dependent isolators, also known as Faraday isolators, are mainly composed of three parts: a polarizer, a Faraday rotator, and an analyzer (set at 45° to the polarizer axis). Polarization-independent isolators typically consist of a birefringent crystal (or polarizer), a Faraday rotator, and a half-wave plate. These are usually used in fiber lasers to effectively maintain the stability of the optical system. Made with high-quality magneto-optic crystals, these isolators offer low absorption, high extinction ratio, and low loss, ensuring excellent and reliable performance. The peak isolation can reach up to 45dB, with an aperture size up to 45mm. The typical transmission rate can reach 95%, and all products are customizable according to customer requirements.

Dimensional Drawing

Polarization state reference

All models of free-space isolators will non-reciprocally rotate the polarization state by 45° along the polarization plane.

An additional 1/2 waveplate can be provided upon request to alter the output polarization state.

Polarization-dependent isolators beam selection

All models of free-space isolators will non-reciprocally rotate the polarization state by 45° along the polarization plane.

An additional 1/2 waveplate can be provided upon request to change the output polarization state.
