S5FC

S5FC version 1.2.0 is a dedicated control suite developed by THORLABS Inc. to operate the company’s S5FC Fiber-Coupled Benchtop SLD Light Sources, placing it in the scientific instrument software category. The package combines a full graphical user interface with low-level drivers and software development kits for both LabVIEW and C++, enabling researchers to integrate the broadband light source into automated test rigs, coherence-domain imaging setups, or fiber-sensor characterization benches without writing custom communication code. Typical use cases include aligning interferometers, stabilizing optical coherence tomography systems, sweeping center wavelengths for component testing, and logging real-time spectral output for process monitoring. Because the kit exposes the same command set across the GUI and both SDKs, users can start with manual control, then migrate identical instructions into production scripts or NI LabVIEW sequences when higher throughput is required. Version 1.2.0 is the first public release, so laboratories already deploying earlier firmware revisions can move directly to this build to obtain the unified programming interface and updated driver stack. The installer places certified Windows drivers that enumerate the benchtop unit as a virtual COM device, eliminating the need for additional hardware adapters and ensuring that timing-critical routines written in C++ meet microsecond-scale response specifications. Although the title is available for free on get.nero.com, downloads are supplied through trusted Windows package sources such as winget, guaranteeing that the latest build is always fetched, and the platform supports batch installation of multiple applications for streamlined lab deployment.
