PEKA light engine®
White light for transmitted illumination on any microscope
Solid-state replacement for tungsten-halogen white light transillumination sources
The PEKA light engine is Lumencor’s white light illuminator designed for use as a transmitted light source. White light is generated by merging the outputs of three solid state light sources. These include Lumencor’s proprietary, luminescent light pipe source. The white light output has a correlated color temperature of ~6000K that does not change when the output is electronically attenuated. No superfluous UV or nIR light is generated. And unlike phosphor-based “white LEDs”, the PEKA does not generate background in the facing epifluorescence detection lightpath.
Unlike conventional tungsten-halogen lamps, the PEKA produces stable light output as soon as it is switched on — there is no warm-up time. And the downtime and expense of bulb replacements is eliminated. Power consumption is reduced too. PEKA consumes about 15 watts at full output compared to 30W for a typical tungsten-halogen illuminator. PEKA couples directly to all major brand microscopes and is passively cooled for vibration-free operation. PEKA may be manually operated or electronically gated for millisecond timing control.
