Newport’s model 77529 is a fiber optic f/# matcher. When light from a fiber optic is sent directly into a monochromator or spectrograph, energy is lost if the output angle of the fiber optic is larger than the input angle of the monochromator and/or if the fiber size is larger than the slit size. The 77529 works by increasing the f/# of the beam from a fiber optic cable by 2x, matching the fiber output to the input required by Oriel monochromators and spectrographs. The advantage of using the 77529 is to increase throughput while decreasing stray light inside the instrument. For imaging applications, the image is magnified by a factor of 2x. The 77529 may also be used at the output of a monochromator to couple light into an output fiber – in this case, the slit image is de-magnified by a factor of 2x. This adapter's reflective optics operate from 190 nm to 24 µm, and it is suitable for use with fused silica fibers (not glass fibers). The 77529 has precise X, Y and Z focus adjustment for optimal alignment of the fiber image with the monochromator slit. It has a 1.5-in. series female quick connect flange and an adapter to hold any Oriel fiber with standard or quick connect 11-mm ferrule. This adapter also has a #1/4-20 threaded hole, as rod mounting is suggested for additional support.
Models 77855 and RF-ADAPT adapters hold the rectangular end of our Large Slit Rectangular to Circular Fiber Optic Bundles at the input of Oriel monochromators and spectrographs or other flanged components. The fiber replaces the slit, and these adapters do not require a fixed slit holder for mounting, as they couple directly to the aperture of the monochromator.
When used at the input, much of the light from the fiber overfills the grating and is lost. This is especially true for glass bundles. Even so, the simplicity and convenience of this technique ensure its application when there is plenty of light, and stray light is not a major concern. However, when this is not the case, use the
The 77358 couples the rectangular end of a Large Slit Fiber Bundle to a monochromator slit. If working with a fused silica bundle, use the 77358 with the Focusing Lens Assembly, model
Model 77860 adapter couples a single channel Oriel fiber bundle to the input of Oriel monochromator or spectrographs for our 11-mm standard ferrules . This adapter holds fiber bundles with an 11-mm standard ferrule termination. It holds the bundle against the slit of any Oriel monochromator or spectrograph (the instrument must have a fixed slit assembly). This coupler can also be used to hold single fibers at the entrance slit to a monochromator or spectrograph, with the addition of the
Model 77863 fiber adapter is used for Oriel fiber bundles with an 11-mm quick connect ferule termination. The female flange on this adapter couples to the male flange of a fixed slit holder and holds the fiber in the slit plane – the fiber replaces the slit. The 77863 is compatible with most Oriel monochromators and spectrographs.
