Product information "HPUC-2A Laser to Fiber Couplers"
Adjustable Focus; 200 to 2100 nm; Power >5 to >100 W CW; Coupling Efficiency >70% to >90%; Fiber Type SM, MM or PM
HPUC-2A adjustable focus source couplers are ideal for situations where optical coupling efficiency is critical, such as in high power applications. A special connector allows the spacing between the fiber and lens to be precisely controlled without rotating the fiber. This is ideal in polarization maintaining applications, as the polarization axis does not change. The adjustments allow to compensate for any change in wavelength or beam wave location, thus further optimizing the coupling efficiency. The optimized coupling efficiency leads to minimized heating of the fiber, especially important with high power. Adjustable focus couplers are available with a variety of lens types and fiber types. Internal surfaces are angle polished and/or AR coated to minimize backreflection. Typical backreflection levels are -40dB, with -60dB available for certain options. In our OZ Optics portfolio you also find fiber patchcords with adjustable FC/PC connectors only. For more information please see the patchcord section or contact us for further assistance.
