High power polarization dependent free space isolator 461/689/813 nm (rotator/rotator)

High power polarization dependent free space isolator 461/689/813 nm (rotator/rotator) HPDFSI series

Visible light free space isolator 400-2000nm

This new type of visible light isolator is used to protect light sources from back reflection. Backreflection can damage the laser source or cause mode hopping, amplitude modulation, or frequency shift. In high-power applications, back reflection can also cause instability and power spikes. Our visible light isolator is a passive optical device that preferentially transmits light in a single direction, shielding the back reflection of upstream optical components. It is polarization related.

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
