Lumencor PEKA Light Engine

Lumencor’s PEKA Light Engine provides a high-performance, mercury-free, turnkey alternative to conventional tungsten-halogen light sources for transmitted light microscopy, brightfield microscopy and other applications.

Unlike tungsten-halogen microscope lamps, the solid-state unit produces stable light output at the flip of a switch — there is no warm-up time. The white light output is spectrally invariant. The output correlated colour temperature is ~6000K and does not change with intensity adjustments.

White light is generated as a composite of outputs from three spectrally constrained solid state sources: red (610–650 nm), green (510–600 nm) and blue (420–480 nm). There are no superfluous and potentially damaging ultraviolet or infrared outputs. Output power is ~90 mW total, 420–650 nm.

The light sources do not contain phosphors with the potential to generate background signals via excitation from the facing epifluorescence light path and the product does not need to be left running between imaging sessions. It enables electronic adjustment of light intensity without neutral density filters, with constant colour temperature output at all intensity settings.

The system features low power consumption (~11 W at full output) with no routine maintenance or consumables required. It weighs 1.5 kg and measures 90 x 150 x 110 mm.
