Innovation In Optics Compact Fiber Couplers

The versatile and powerful LumiFiber™ devices are ideal for fiber optic applications in industrial, medical, and laboratory equipment. The couplers incorporate LumiBright™ light engines with interfaces for light guides or fiber bundles. The Model FC 1700A-100 supports up to a 2 mm fiber bundle using an SMA 905 connector. A LumiFiber™ provides a reliable, compact, homogenous, and robust light source with up to 25 watts of visible/UV/NIR light – ideal for use in high-performance endoscopes and borescopes.
Thermal management is key to performance and lifetime. Multiple options are available. Wavelength Opto-Electronic is the partner of Innovation In Optics brand of compact fiber coupler for Singapore.

LumiFiber™ 1180D & 1700A

The LumiFiber 1180D & 1700A will support up to 2.0mm fiber bundle. There are options for 1 to 4 LED die in single or multicolor configurations.

LumiFiber™ 2400B-4 & 2400B-5

The maximum coupling efficiency for the Model 2400B-4 requires the use of a fiberoptic or liquid light guide with equivalent specifications for both the nominal values of Numerical Aperture (NA₀) and Clear Aperture (CA₀). When the light guide design parameters of NAf or CAf are smaller than the nominal values of the Model 2400B-4, the coupling efficiency is reduced by the square of the ratios, (NAf/NA₀)² and/or (CAf/CA₀)². Other factors that contribute to coupling efficiency are the reflectance loss at the face of the fiberoptic or light guide, as well as the packing fraction when using a fiber bundle.
