Prior Scientific Lumen 200 Fluorescence Illumination System

The Lumen 200 Fluorescence Illumination System from Prior Scientific is a powerful alternative to 100 W mercury and halogen lamp houses for microscopy applications. The combination of Prior’s 2000 h life, 200 W metal arc lamp and 2 or 3 m liquid light guide provides high levels of versatility and illumination power.

The product utilises a metal halide lamp, rather than the more traditional high-pressure mercury or xenon burners. This means 2000 h of stable output, compared to a maximum of 300 h for a mercury lamp. The use of a liquid light guide means there is little heat transfer, helping to eliminate thermal drift during time lapse experiments. The unit also incorporates a variable light attenuation control to reduce the potential of bleaching and phototoxicity.

Prior Scientific also offers the Lumen 220 Fluorescence Illumination System, with extended wavelength in UV and IR. Fluorophores requiring light in the 360 nm and below range will see significant increases in signal strength from the Lumen 220 as compared to the Lumen 200 models.
