COB-6500 Fiber coupled LED Light Source The COB series comprises high power LED light sources with peak wavelengths that range from UV to NIR. They are co nceived as user friendly, compact and silent tools, being ideal for fluorescence, spectroscopy and general fiber illumination applications. These light sources have been designed to obtain a high coupli ng efficiency to optical fiber through a selectable SMA/FC connector. In addition, they can be operated either in continuous (CW) or pulsed modes.

Operation Modes Connect a proper power source (included with the light source) prior to operation. The light source includes two controls on the front. The MODE switch on the right sets the operation mode between ON (left), OFF (centre) and PULSED (right). The left knob controls the intensity in ON mode (switch on the left position). The intensity can be adjusted between 20% (fully counter-clockwise) and 100% (fully clockwise) of maximum intensity. In PULSED mode (switch on the right position), the intensity can be controlled using a PWM (pulse width modulation) signal through the PWM input connector...
