As the first company to introduce LEDs into fluorescence microscopy, CoolLED has developed a comprehensive understanding of the complexities of configuring and selecting filter sets for samples which have multiple stains. These ’multi-band’ filters must have a corresponding absorption and emission band for each stain and the bands must be kept spectrally separate to ensure there is no overlap.
CoolLED’s innovation comes from recognizing that all the stains used in multi-band work can have their absorption bands divided into four separate groups across the spectrum due to the restricted bandwidth available. This has allowed the development of a patent-pending, wavelength-grouping concept which makes it possible to deliver more power in an efficient four channel system.
With its unique 16 selectable LED wavelengths, the pE-4000 ensures optimum compatibility with all single and multi-band filter sets. The flexibility and extensive functionality of the pE-4000 broadens the range of illumination options in core facilities.

The compact pE-4000 Light Source houses all the LEDs, their combining optics, thermal management and control electronics. A dual mode control pod gives manual control in either White or Advanced modes. Light is delivered to the microscope by either a single liquid light guide (LLG) or fiber. LLGs can be used in conjunction with CoolLED’s pE-Universal Collimator which can accept a microscope adaptor from CoolLED’s extensive range. For further information go to the Downloads tab
