Models 77860 and 77863 adapters couple a single channel Oriel Fiber Bundle to the input of Oriel Monochromator or Spectrographs for our 11 mm standard ferrules and Quick Connect ferrules. Models 77854 , 77855 , 77856 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.
77860 Fiber Adapter
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 (instrument must have a fixed slit assembly). We also use this coupler to hold single fibers at the entrance slit to a monochromator or spectrograph, with the addition of the 77670 or 77675 Converter on the end of the fiber. These converters change an SMA or ST termination into an 11 mm standard ferrule.
77863 Fiber Adapter
Use the 77863 for Oriel Bundles with an 11 mm quick connect ferrule termination. The female flange on the 77863 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 works with most Oriel Monochromators and Spectrographs. For the MS257TM, we offer Monochromator Fiber Adapters for MS257™ Spectrograph.
77854,77855 and 77856 Fiber Adapters
These fiber adapters hold the rectangular end of the “Large Slit” Fiber Bundles at the input of Oriel Monochromators. The fiber replaces the slit. These fiber adapters do not require a fixed slit holder for mounting; they couple directly to the aperture of the monochromator (see Fig. 1).
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 ensures its application when there is plenty of light, and stray light is not a major concern. When this isn’t the case, use the 77358 Adapter. When you use the 77854 /5/6 fiber slit at the output, the bundle accepts all the light, which falls on the “fiber slit.” Be sure to choose a matching input fixed slit, or set the variable slit to match the “fiber slit.”
77358 Fiber Adapter
The 77358 couples the rectangular end of a Large Slit Fiber Bundle to a monochromator slit. If you are working with a fused silica bundle, use the 77358 with the Focusing Lens Assembly. The 77330 will then focus the bundle’s image onto the monochromator input slit. For glass bundles, you may couple the bundle directly to the monochromator slit using only the 77358 ’s spacer tube (the 77330 is not required).
