SuperK SPLIT spectral supercontinuum splitter

The SuperK SPLIT is a passive filter which allows the SuperK spectrum to be divided into two spectral outputs. This is important in applications where light from one sub-area of the spectrum is desired and light outside this spectrum is parasitic.


  • Separation of VIS from NIR
  • Industrial proven fiber coupling
  • Various fiber interfaces
  • Plug & play compatible
  • Modular and integrable into the SuperK source

Wavelength split

As standard, the SuperK SPLIT has two outputs: Visible and nIR. However, the choice of the “split” in the spectrum can be user-defined to be anywhere in the SuperK spectrum. Additionally, the SPLIT can be fitted with extra filters in the two beam paths - either from the factory, or by equipping it with our external filter mount for further flexibility.

Single mode fiber delivery

SuperK_CONNECTThe SuperK SPLIT is compatible with our SuperK CONNECT high performance fiber delivery system that comes complete with broadband fibers and a range of termination options such as FC/PC connectors or high quality collimators. Interfacing is handled by the CONNECT fiber coupling block that ensure easy and stable single-mode coupling that can be disconnected and reconnected without alignment.
