PRODUCT DESCRIPTION:
Adjustable focus source couplers are ideal for situations where optimum
coupling efficiency is critical. 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.

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. Contact OZ for more
information.
