Near-IR optical isolator

1310/1550nm free space single-stage/two-stage isolator

The fiber optic isolator made using Faraday rotation effect consists of an isolator core, a branch fiber collimator, and a sleeve. Components such as outer magnet tubes. Rotating magnetic cores with different working wavelengths can be designed as needed. If the isolation of a single-stage iron core is not sufficient, a two-stage isolator core can also be made. Idealoptonics can provide 1310nm/1550nm free space single-stage/two-stage isolators.

Free space isolator (355-4500nm customizable)

Free space isolators can be divided into two categories: polarization dependent and polarization independent. Polarization related isolators, also known as Faraday isolators, are mainly composed of three parts: polarizer, Faraday rotator, and analyzer (at a 45 ° angle to the polarizer's polarization axis). Polarization independent isolators are mainly composed of birefringent crystals (or polarizers), Faraday rotator, and half wave plates. They are commonly used in fiber lasers to effectively maintain the stability of the optical system. Using high-quality magneto-optical crystals with features such as low absorption, high extinction ratio, and low loss, the product has excellent and reliable performance. The maximum peak isolation is 45dB, the maximum aperture is 45mm, and the typical transmittance can reach 95%. All products can be customized by customers.

High power free space isolator 980/1030/1064/1080/1150/1310/1550/2000nm

A high-power infrared isolator is a unidirectional device used to protect a light source from possible back reflections or signals in an optical system. Reverse reflection can damage the laser source or cause mode hopping, amplitude modulation, or frequency shift. In high-power applications, reverse reflection can cause instability and power peaks, and even damage the light source. Our high-power isolator is a passive magneto-optical device that preferentially transmits light in a single direction and shields upstream optical devices from reverse reflection. The operation of the isolator is based on the Faraday effect.
