The pE-4000 sets the standard as the universal illumination system for fluorescence microscopy. The system has 16 selectable LED wavelengths that can be matched to the filters and fluorophores of almost any microscope, making it the broadest spectrum of illumination available.
For the user who wants consistency and ease of use with simple on/off and intensity buttons, the pE-4000 can be operated as a ‘White’ illumination system.
For the user who wants total control over the excitation source to improve imaging, individual wavelengths settings can be selected and controlled in “Advanced” mode.
Light is delivered to the microscope by either a single liquid light guide (LLG) or fibre. LLGs can be used in conjunction with CoolLED’s pE-Universal Collimator which can accept a microscope adaptor from CoolLED’s extensive range.
- Broadest LED spectrum available: 365-770nm – match LED peaks to existing microscope filters
- Four channel wavelength-grouping design matches with all commercially available dual, triple, and quad filters
- Individual control of selected LED wavelengths – less background, no filter wheel or shutters
