CODE GENERATOR


For in vivo optogenetics experiments there is a need to illuminate the tissue with specific pulses of spectrally different lights using the same fiber. To put it simply, the light from different fiber coupled LEDs or lasers needs to be combined into one beam and coupled to an optical fiber leading to a fiber-optic implant or cannula. Our patent pending Light Spectrum Mixer provides a compact, connectorized package with highly efficient coupling and low polarization dependent loss (PDL), ideal for multimode fibers.

The same device can be used in the opposite direction as a light spectrum separator. The concept of a spectrum mixer or splitter is analog to the concept of a wavelength division multiplexing and demultiplexing in optical telecommunication.

NB: Our standard products assume the use of identical fiber diameters and identical receptacle codes. However, this can be customized if needed at extra cost.
