Notes:

1. Above data are test results of UV-VIS-NIR fiber combiner without connectors.

2. Lfiber’s UV-VIS-NIR fiber combiner (optical power combiner) is wavelength-insensitive and mode-insensitive over a broad wavelength range. Also, it can be designed to have an optimum performance for specific wavelength range according to your applications. So please tell us the accurate operating wavelength range if possible.

3. Different core/cladding diameters and numerical apertures (NA) of the input/output fibers are optional, as a result, the combiners may have different transmission efficiency.

4. Please specify the operating power if the UV-VIS-NIR fiber combiner (optical power combiner) operates on a high-power continuous-wave (CW) laser, it may need a heat sink design for the package.

5. If a high-quality output beam (with fewer speckle hot spots and more uniform energy intensity profile) is needed, the large core fiber combiner (optical power combiner) can be integrated with LFIBER’s In-line Laser Speckle Reducer (Fiber Optical Beam Homogenizer) to make a hybrid component.
