Design of optical fiber assemblies for spectroscopy
Fiber-optic bundles are perfectly adapted to perform diffuse reflectance spectroscopic measurements.
KeyFeatures
- Customer-specific designs,
- Fibers with core diameters from 50 μm to 1000 μm,
- Broad spectral ranges: UV-VIS or VIS-IR,
- End configurations: round, square, linear or other geometry,
- Fan-out: single or multi-fibers per leg,
- Array: matches the entrance slit of a spectrometer or monochromator,
- Mapping: random or coherent,
Fiber optic bundles usually consist of optical fibers in a round or linear configuration combined in a hand-piece or in an SMA905 connector to match the entrance slit of most spectrometers.
These assemblies are ideal for reflectance spectroscopy and fluorescence spectroscopy. They can also be used with monochromators.
This is a 100% customizable component: fiber types, number of fibers, detection geometry (round, square or any geometry), end configuration (hand piece, SMA connector…), mapping of the fibers (random or coherent)… Everything is possible!
