A SLED is an edge-emitting light source. One of the exceptional qualities of the SLED is its high output power and low beam divergence, similar to a laser diode, but with a broad emission spectrum and low coherence, similar to a LED. SLEDs are similar in geometry to lasers but have no built-in optical feedback mechanism required by laser diodes.

SLEDs have a much higher gain, higher current density and stronger non-uniformity of photons and carrier density distribution inside the active region. SLEDs are essentially highly optimized LEDs. While SLEDs operate like LEDs at low current levels, their output power increases superlinearly at high currents.

Applications include optic components testing, fiber sensor systems, fiber optic gyroscopes, optical computed tomography (OCT), biomedical imaging devices.

These are our fully featured, low-high wattage sources of CW radiation. A range of optical accessories support these sources (fiber assemblies, focusing lenses, bandpass filters, beam apertures), which are extremely adaptable and are suitable for most research applications.

These high efficiency illuminators have outputs matched to F/2 fused silica fibers. An aspheric focusing lens assembly ensures a tight, uniform image of the arc or filament. We offer illuminators to run deuterium, arc, quartz tungsten halogen and infrared sources.

Solar Simulators offer the possibility of projecting how solar radiation will affect materials and finishes intended for outdoor use. We offer a wide range of Class A or B Solar Simulators from 150W to 1600W with uniform, collimated output beams. Flood Exposure Sources are also available to expose most photoresists, polymer cross-linking and novel resists, and for deep ultraviolet studies.
