Product description

The pE-4000 sets the standard as the universal illumination system for fluorescence microscopy.  The system has 16 selectable LED wavelengths across 4 channels that can be matched to the filters and fluorophores of almost any microscope, making it the broadest spectrum of illumination available. The CoolLED pE-4000 now benefits from our award winning sustainable Green technology and delivers enhanced intensity at your microscope sample plane with a significant reduction in energy consumption, and is supplied with a 3 year warranty after registration.

The pE-4000 offers:

  • 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
  • Integrated with many imaging software packages - can be incorporated into all experimental parameters
  • Instant on/off – no shutters required, no warm up or cool down
  • Stable & repeatable – reliable and consistent results
  • Wide range of Microscope Adaptors – fits most microscopes
  • Precise intensity control in 1% steps (0-100%) – no ND filters required
  • Excellent uniformity over field of view – fixed and stable, no alignment necessary
  • Long lifetime – expected to exceed 25,000 hours of operating time


  • Power requirements
