The Prior Scientific Lumen 200 Fluorescence
Illumination System is a powerful, cost effective alternative
to standard 100 Watt mercury and halogen lamphouses. The
combination of Prior's proprietary 2,000 hour life,
200 watt metal arc lamp and two or three meter liquid
light guide provide unrivalled versatility and illumination
power.
Designed
to mount remotely via a two or three meter liquid light
guide the Lumen 200 eliminates heat transfer to the
microscope, minimizing thermal drift and aiding image
stability in long term experiments.
“The new metal halide illumination technology from Prior provides ample
light for imaging in fluorescence microscopy at virtually any level, from live
cells to well-stained fixed tissues. Due to great temporal stability, these light
sources enable serial image collection in time-lapse sequences over extended
periods without the annoying fluctuations in intensity that are seen with
many other illumination sources. Customer service from Prior matches their
top-of-the-line product lineup.”

The digital videos presented below of cells in culture, demonstrates the Lumen Fluorescence Illumination Systems superior brightness and unrivalled stability. The experiments used to obtain the videos utilized a Lumen Fluorescence Illumination System and an Olympus DSU (Disk Scanning Unit) confocal microscope. The digital videos include:
Fox lung cells with EGFP fused to the microtubule-binding protein EB3, Opossum kidney cells with Katushka fluorescent protein mitochondrial expression, Pig kidney cells with EGFP-Tubulin and mCherry-H2B and in the final segment a translocation of annexin (A4) to the membrane in HeLa cells.
Prior Scientific also offers the Lumen 220 Fluorescence
Illumination System with extended wavelength in UV and IR. Fluorophores requiring light in the 360nm and below range will see significant increases in signal strength from the Lumen 220 as compared to the Lumen 200 models.
