Full Power across the Spectrum

Comparison of output from Chroma's filter set 61000 using the PhotoFluor® II lamp (left) and a new 100W mercury arc lamp (right).

An optimal light source for fluorescence microscopy should provide sufficient output across the necessary spectrum for contemporary fluorochromes. It should be easy to use, and require little or no alignment. The PhotoFluor II provides high output from 340 nm to 650 nm with enough power in the UV for strong DAPI or Hoechst imaging. It combines a powerful light engine with quiet operation and no vibration. The nature of the metal halide source eliminates the need for alignment and ensures long lamp life (in excess of 1500 hours). A DC power supply stabilizes lamp output over time for minimal fluctuation during time-sensitive experiments. The PhotoFluor II was designed to meet optimal specs by bringing together experts in the microscope industry, researchers in laboratories, and cutting edge electrical and mechanical engineers. It is built in the USA in Vermont.
