Newport MKS Optical Fiber Adapter, Monochromator, Rectangular Fiber Bundle RF-ADAPT

The RF-ADAPT Rectangular Fiber Bundle Adapter provides a simple solution to optimally couple Oriel® circular to rectangular fiber bundles to the input flange of any Oriel monochromator. Effectively coupling a fiber into an instrument can be difficult, as light diverges upon leaving the fiber. The most common solution is to use lenses to focus output light into the input aperture of the instrument. The RF-ADAPT simplies this, by mechanically coupling the rectangular ferrule of a circular to rectangular fiber bundle as close to the input slit of an Oriel monochramator as possible. This minimizes the distance output light from the fiber has to travel, reducing losses due to divergence and stray light. Users do not have to worry about calculating end of fiber to input slit distances and finding a lens with the right focal length-just install the fiber into the adapter and connect to the monochromator. The RF-ADAPT has a 1.5 inch female flange for easy coupling to any Oriel monochromator.
