The Newport NRC F-915 Locking Base is a precision positioning platform engineered for optical alignment and fiber coupling applications. Available in F-915 and F-915++ variants, this component delivers five-axis motion control with sub-micron resolution for optimizing coupling efficiency to single-mode and multimode fibers. The kinematic design minimizes vibration and drift, making it essential for demanding laboratory environments where stability and repeatability are critical.
