AP Technologies also offers the FibercoupLED12 (FC-LED12) LED-based light source from Adaptive Lighting.


Adaptive's FC-LED12 consists of a compact (W 70mm H 55mm L 70mm) light source containing 12 individually configurable High Brightness LED sources thereby providing multiple pre-defined spectral outputs. The integrated control module allows control of the light source via PC or laptop using the intuitive Graphical User Interface (GUI).


OEM users can specify the wavelengths of the individual LEDs from 355nm to 2,500nm with the option of using multiple die of the same wavelength to increase power within particular bands. Each LED channel can be operated in Continuous On Mode with 1024 Bit control or via External TTL Strobe Mode.


The light source is available as a fiber-coupled module with SMA, 3mm or 5mm lightguide adaptors and a range of focusing and collimating optics.
