Ocean Optics LLS User Manual
LLS Series LED Light Sources
Installation and Operation Instructions
Description
Ocean Optics’ LED Series light sources (LLS) are engineered to be a versatile tool for scientific and
general lighting applications. Light is coupled directly into a fiber with the highest efficiency possible
via the SMA 905 connection. You can adjust the optical intensity in continuous (CW) and pulse
modes. The LLS Series support a ‘pulse mode’ to allow higher current and thus higher optical power
when in pulsed mode. The LLS module is designed to accommodate external control of intensity,
pulse and lamp on/off. This system also has the ability to have interchangeable light modules.

Controls
The LLS Light source features two control knobs on the front. The knob on the right controls the input
mode. The switch turned fully clockwise is the continuous mode, “off” is the middle po sition and fully
counter-clockwise is pulse mode. Remember that an external trigger is required for pulsing. This can
be accomplished via a cable connected to your electronics, or through an optional USB controller.
The left knob controls intensity. Turn clockwise for maximum intensity. The intensity control will
work in both pulse and continuous modes.
