CoolLED’s pE-300white offers intense, broad-spectrum LED illumination for imaging most common fluorescent stains.  The pE-300white Light Source can be fitted directly to the microscope or specified with a liquid light guide.  The system is a mercury-free alternative that is safer, more controllable, and repeatable than conventional high-pressure gas discharge illuminators.  Spectral coverage is from the UV (DAPI excitation) to the Red region (Cy5 excitation). The system is perfect for hospital and regular research laboratory environments.

With an expected lifetime in excess of 25,000 on hours and a comprehensive range of microscope adaptors, the pE-300white can be fitted to most current and older microscopes and operate for many years without aligning or replacing bulbs. The result is a safe, convenient illumination system without any additional operating costs.


There are two pE-300white configuration options:

Direct-fit  for connecting to a microscopes – by selecting from a range of microscope adaptors  which covers all current and most older models.  A simple once only adjustment will allow optimisation to the optical path of the microscope.

Liquid Light Guide with a fixed 3mm diameter, liquid light guide.  An optional pE-Universal Collimator can be specified in conjunction with a microscope adaptor if required.
