FCLS-LED-840 fiber-coupled LED light source has a nominal wavelength of 840nm. It can work in continuous, pulse and external trigger mode. The light source uses fan-based heat dissipation, and thanks to the high quality lamp, efficient heat treatment and reliable circuit design, the output light power is very stable. It outputs stable and high intensity continuous light in continuous mode, and pulsed light with adjustable frequency in pulse mode; both modes support 0~100% continuous linear regulation of output light intensity. The user can use the USB interface to control working frequency, intensity ratio and duty cycle in external trigger mode. FCLS-LED uses a standard SMA port as its default output interface. It also supports FC, ST and other optical fiber interfaces.
