New video explains TTL and Analogue Modes of pE-800 Series and pE-4000
CoolLED Illumination Systems are known for offering a multitude of control options, from manual to software operation. In the realm of high-speed microscopy, encompassing not just fluorescence microscopy but also cutting-edge applications like optogenetics, the value of TTL and analogue options cannot be overstated.
This is because they increase LED switching speeds due to bypassing latencies introduced from PC operating systems.
Both the pE-800 and pE-4000 models offer this advanced control capability, with TTL providing precise on/off control for each LED, while analogue enables smooth adjustment of irradiance from 0 to 100%.
In our latest tutorial video, Technical Content Specialist Dr Isabel Goodhand, explains how to control the pE-4000 and pE-800 Series.
About the pE-4000 Microscope Illuminator
The pE-4000 sets the standard as the universal Illumination System for fluorescence microscopy.
The system has 16 selectable LED wavelengths across four channels that can be finely controlled and matched to the filters and fluorophores of almost any microscope, making it the broadest and most versatile illumination system available.


About the pE-800 Microscope Illuminator
The arrival of the pE-800 sees LEDs take centre stage as the widefield illumination method of choice.
Featuring eight individually controllable LEDs and lightning fast TTL switching, the pE-800 delivers the highest quality data with minimum total cost of ownership.

CoolLED specialises in LED microscope lighting and, since our team of four introduced the first commercially available LED microscope illuminator in 2006, we have led the way in designing and manufacturing cutting edge LED Illuminators for Microscopes using the latest technology.
