A special connector allows the spacing between the fiber and lens to be precisely controlled without rotating the fiber. This allows one to compensate for any changes in wavelength or beam waist location, thus further optimizing the coupling efficiency. 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. -60dB is available for certain options. OZ Optics also sells fiber patchcords with adjustable FC/PC connectors only. Contact OZ Optics for details. 09/99 OZ Optics reserves the right to change any specifications without prior notice.

NOTE: To determine the best laser to fiber source coupler for your application please complete a Laser to Fiber Delivery System Questionnaire. OZ Optics will then recommend a coupler based on your response. Unit prices range for couplers are approximately $450USD for typical applications with delivery being between 2 and 4 weeks after receiving your order (ARO). Unit prices for adjustable patchcords are $160USD for each adjustable connector plus the fiber price. Delivery is 2 - 4 weeks, ARO. Quantity discounting and blanket orders can be arranged.
