    Optimizing Illumination with Optical Filters in Fluorescence and Raman Systems

    NEW Tech Note: orientation to optimize fluorescence excitation strategies for different types of light sources (white light, LED, and laser) in life science applications (cell fluorescence and Raman).

    Assuring a good signal-to-noise ratio in systems for cell fluorescence or Raman signal detection depends strongly on the details of the excitation or illumination system. This Technical Note summarizes optimal approaches when using the three main types of illumination sources in common use for fluorescence – broadband, white-light sources (such as arc lamps), LED-based light engines, and lasers.
