FLG Series Optical Fibers and Fiber Bundles, 200–2400 nm, SMA905, NA 0.22
FLG SeriesDesign Tools
Quartz fibers and 19-fiber bundles for coupling light into monochromators and sample chambers.
FLG series fibers and fiber bundles connect light sources, samples and detectors to Omni-λ series monochromators and sample chambers through BFC series fiber couplers, making it simple to assemble an optical system. Single fibers come in UV (200–1100 nm) and IR (350–2000 nm) versions with 50–600 µm core diameters; bundles combine 19 fibers of 200 µm with round or SMA905 ends. The x in each model number denotes the fiber length.
Key Features
- Single quartz fibers with 50, 100, 200, 400 or 600 µm diameter
- UV version for 200–1100 nm and IR version for 350–2000 nm
- Fiber bundles of 19 × 200 µm fibers covering 200–1100 nm up to 400–2400 nm
- Bundle input ends of Ø13 mm, Ø10 mm or SMA905; output end SMA905
- NA 0.22, 25° full divergence angle
- SMA905 connectors as standard; FC or other connectors optional
- Accessories: 74-UV fiber collimator and TLS-SMA905-GJ fiber focusing accessory
Typical Applications
- Fiber coupling of light sources to monochromators
- Collecting light from samples into spectrometers
- Remote and flexible spectral measurements
- Building modular spectroscopy setups with sample chambers
