F-915 In Stock

The F-915 by Newport is a Single-Mode Fiber Coupler meticulously engineered for the purpose of facilitating the coupling of laser beams in single-mode configuration into a bare single-mode optical fiber. This coupler embodies precise sub-micron positional capabilities, thereby contributing to the attainment of optimal single-mode coupling efficiency. The core element of this coupling mechanism is the fiber chuck, which is securely held within a three-axis positioner. The F-915 facilitates intricate translational adjustments and focal refinements, prerequisites for accurately aligning a concentrated laser beam onto the terminal end of the fiber.

The F-915 boasts finely tuned adjustment screws featuring a high-resolution specification of 100 threads per inch (TPI). These screws facilitate seamless two-dimensional translation adjustments (XY adjustments), while the inclusion of a knurled knob, operating on an 80 TPI thread, facilitates axial movement along the Z-axis. The pursuit of sub-micron levels of accuracy necessitates the incorporation of a kinematic tip and tilt stage, a component which empowers pivotal movements of the lens and fiber-holder assembly. This stage is supported by 100 TPI adjustment screws, enabling meticulous control over angular adjustments. This intricate tilt manipulation introduces a secondary level of beam translation adjustments. The F-915 adheres to a fixed nominal optical axis height of 3 inches. In addition, its base is equipped with a pattern of tapped and clearance holes, a design feature that facilitates secure mounting onto compatible breadboards and tables.
