PEKA light engine®

White light for transmitted illumination on any microscope

PEKA light engine

Power and performance in a simple,
white light producing light engine

The PEKA light engine is Lumencor’s white light illuminator designed for use as a transmitted light source. PEKA couples directly to any major brand microscope and has no fan so produces no vibrations. Spectrally pure white light is generated with no harmful UV or NIR. PEKA may be manually operated or electronically triggered for millisecond timing control.

PEKA light engine integrates multiple solid state light sources. These include Lumencor’s proprietary, luminescent light pipe source. The red/yellow/green/blue (RYGB) output is unique in its ability to maintain constant color temperature throughout all gain settings.

Lumencor’s white light PEKA can be driven at the same color temperature, regardless of the neutral density selection. This represents the only while light product on the market that can provide a consistent color temperature, regardless of output power. PEKA is a robust illuminator and a powerful alternative to the more traditional tungsten-halogen lamp.
