1064nm Large Aperture Free-Space Optical Isolator

The HPISO-FS-100-12-1064-C-A09 free-space isolator is available in two types: polarization-dependent and polarization-independent. The polarization-dependent isolator, also known as the Faraday isolator, is composed of three parts: a polarizer, a Faraday rotator, and an analyzer (with its polarization axis at 45° to the polarizer's axis). The polarization-independent isolator typically consists of a birefringent crystal (or polarizer), a Faraday rotator, and a half-wave plate. It is commonly used in fiber lasers and effectively maintains the stability of optical systems. The isolator uses high-quality magneto-optic crystals, offering characteristics such as low absorption, high extinction ratio, and low loss. It delivers outstanding and reliable performance, with a maximum peak isolation of 45 dB, an aperture of up to 45 mm, and a typical transmission of up to 95%. Customizations are available upon request.
