The pE-100 system is designed for fluorescence applications requiring a single LED excitation wavelength.  It is perfect for clinical applications such as routine screening, for research applications requiring precise irradiance control and fast-switching, or for electrophysiology applications where light has to be delivered to a specific location. 

The user can select from 20 different LED wavelengths, ranging from the near-UV at 365 nm to the near-IR at 770 nm.  For increased irradiance, a direct fit version is also available, which fits directly to the microscope via a specified adaptor.

There are three standard pE-100 configuration options:

• Direct-fit: The pE-100 is designed to connect directly to a microscope’s epi-illumination port by selecting from a range of microscope adaptors.  A simple once only adjustment will allow optimisation to the optical path of the microscope.
• Liquid Light Guide: The pE-100^{light guide} connects to the microscope via a fixed 3 mm diameter, 1.5 m long liquid light guide.
• Fibre: The pE-100^fibre features an SMA connection for accepting multimode fibres and has been designed with efficient coupling into a wide range of fibre types. The pE-100^fibre also includes excitation filter holders.
