CoolLED Illuminators


CoolLED PE-4000
LED White Illumination System
Principle Use
The pE-4000 sets the standard as the universal illumination system for fluorescence microscopy.

Product Description

The pE-4000 sets the standard as the universal light source for fluorescence microscopy. Users can operate the system as a simple white light source (replacing a conventional mercury-based light source), or as an advanced, fully-controllable, excitation and stimulation source. The flexibility and extensive functionality of the pE-4000 broadens the range of illumination options in core facilities.

At the centre of the pE-4000 is CoolLED’s novel, patent pending, wavelength-grouping concept which offers more power in an efficient system design. Wavelength-grouping ensures optimal compatibility with all single and multi-band filter sets.

White for Simplicity

  • Simple on/off
  • Precise intensity control
  • Easy to use, no training required
  • Pre-sets allowing lab manager to match white spectrum to exiting filter cubes
  • Higher contrast images from matched-white spectrum

Advanced for Control

  • Individual LED wavelength selection
  • Rapid switching between LED wavelengths enables capture of high speed events
  • TTL & USB interfaces with imaging packages
  • Excitation filters can be fitted in optical path for controlled switching with no moving parts
  • Analogue for dynamic intensity control
  • Optical feedback for applications requiring higher stability
  • Internal function generator for electrophysiology and optogenetics applications
  • Compatible with all single and multi-band filter sets

The pE-4000 system:

  • Excellent field uniformity at sample
  • No mercury
  • Long Life: 25,000 hours
  • No bulb changing, bulb alignment or warm up process
  • Quiet operation
  • High efficiency
  • Wide range of microscope adaptors
