We have been producing Faraday optical isolators for over 20 years, offering premier high-power isolators at low cost covering the entire visible to NIR wide wavelength range. These isolators are made with low-loss high-quality TGG crystals. We offer two types of isolators for polarization laser beams. The first type, Fixed Wavelength Isolators, for which peak isolation and peak transmission occur at a pre-defined center wavelength. The typical wavelength dependence is shown in the following graph. The fixed wavelength isolator also has a dual-stage configuration that boosts the isolation to 60 dB. The second type, Adjustable Wavelength Isolators, offers the user the ability to change the center wavelength within a 60 – 90 nm range by adjusting the input and output polarizers. We further offer special configurations having reflection power dumping ports and an integrated tap monitor. If one cannot find the configuration online, we offer build-to-order options. Agiltron has a volume isolator production operation for making custom-specific products with specially-designed quality control tools.
