The In-line Fiber Optics Switch (FOS) was developed for applications and setups where an automatic save-dark (1 light path) or correct for drift (2 light paths) needs to be performed. The manual or TTL electronic controlled shutter is available in the one (FOS-1-inline) or two (FOS-2-inline) light path version.
The FOS typically couples between 2 SMA terminated fibers and consists of 2/4 UV/VIS/NIR collimating lenses and a filter holder for 5 mm thick filters.
The TTL signals are provided by the AvaSpec spectrometer (IC-DB15-2 for AvaSpec-USB1/ IC-DB26-2 for AvaSpec-USB2 needed).
The AvaSoft full software (version 6.2 and higher) supports the correct for drift option for a setup where one of the FOS-2 channels is connected to do a reference measurement (e.g. white tile or cuvette with blank) and the other to do the sample measurement. The long term system drift (lamp or spectrometer, influenced by e.g. temperature is compensated by periodically switching to the reference channel, and using the (changes in) reference data to correct the data measured at the sample channel.
The FOS needs an extra PS-24V/1.25A 24 VDC power adapter. Technical Data
