ANDOVER, England, Aug. 16, 2016 — CoolLED Ltd. has announced the pE-4000 illumination system for fluorescent microscopy. The system has 16 selectable LED wavelengths that can be matched to the filters and fluorophores of almost any microscope. For users who want simple on/off and intensity buttons, the device can be operated as a white illumination system. For users who want total control over the excitation source, individual wavelengths settings can be selected and controlled in an advanced mode. The pE-4000 ensures optimum compatibility with all single and multiband filter sets.
