Fiber Bundles
and Adapters

Universal Fiber Adapter

Several different fiber optic bundles are designed specifically for use with Pricneton Instruments monochromators and spectrographs. Standard bundles included 200 μm diameter fibers in either silica for UV-VIS, or anhydroguide for visible-near IR applciations.

Fibers are arranged as a slit pattern (in 10 mm diameter ferrule) on the spectrograph end, with a round configuration (in SMA 905 connectors) on the sources end. Bundles include a single leg bundle containing 19 fibers, a bifurcated bundle with 7 fibers per leg, and a 4 leg bundle containing 3 fibers pet leg.

Key Features

Long Transfer Distance

Optical fibers are made of a transparent, flexible fiber used to transmit light between two ends of the fiber. This gives them the ability to transmit light over longer distances at higher bandwidths in comparison to electrical cables. Fiber bundles are useful as they allow for a large amount of light to be transmitted in a compact area.

Waveguide Operation

Total internal reflection within the core of the optical fiber allows the fiber to act as a waveguide. This core is surrounded by a transparent cladding which keeps the light in the core by having a lower index of refraction.
