PhotoFluor LM-75

Low-cost, high-power, ultra-stable metal-halide light source

  • Mounts directly to microscope with small footprint
  • High UV output and no flickering
  • Well-suited for routine fluorescence, FISH, and clinical applications

The PhotoFluor LM-75 is the only, direct-mount metal halide light source for fluorescence microscopy. With no liquid light guide and a built-in DC-ballast, the LM-75 delivers the highest possible intensity at the sample and extremely stable output. Together with pre-aligned, user-exchangeable lamp and ultra-quiet operation, the PhotoFluor LM-75 is an ideal replacement for a traditional mercury lamp.
