TIDAS FOS – Fiber Optic Switch for Spectroscopy
The TIDAS FOS meets the specific requirements for fiber-optics based spectrometer systems in process applications like multi-channel process analyzers. To compensate the longterm drift of light sources, switching to an internal reference channel is possible. An optional integrated cuvette holder allows the in-system validation by using standard cuvettes for an integrated holmium filter. Grey filters can be added for each channel, to enable defined attenuation for high dynamic signals.
The channel layout is configurable by design. This allows adapting the TIDAS FOS to the specific needs of a particular application. The linear multiplexer can be used with all fiber coupled light sources for a wide spectral range from UV to NIR and can be adjusted for special customer requirements.
