HPFSI Free Space Isolators

Polarization Sensitive & Insensitive Versions; 1040 nm to 1090 nm; Isolation ≥35 dB; Power Handling ≤80 W; 48 mm x 48 mm x 133 mm The FO(P)I-00 series of free space isolators are featuring options to allow the customer to mount their own fiber pigtailed collimator or beam expander. The OZ Optics tilt adjustment technique gives customers the ability to perform the optical alignment themselves.Isolators are optical devices that allow light to be transmitted in one direction only. They block the source from reflected light, thus preventing any feedback problems, such as frequency instability, relaxation oscillations, amplified stimulated emissions, or optical damage – very critical with the recent dramatic increase in laser output powers, especially in the 1030 to 1090nm wavelength range. To meet this demand OZ Optics has developed a line of high power handling isolators, capable of peak isolation levels of 30 dB to 50 dB for 1030 nm to 1090 nm, depending on the input beam size (with typical beam diameters of 0.4mm to 1.1mm). The isolators come with built-in windows to prevent dust contamination of internal isolator optics. These protection windows are easily removed and replaced by the user. Custom smaller packages can be made for OEM applications – contact us for more details.
