Building on the success of the popular pE-300 Series, the pE-400 is a simple bright white light Illumination System and a controllable, cost-effective replacement for mercury and metal halide lamps. Four powerful LEDs offer intense, broad-spectrum coverage for the most popular fluorophores, ranging from DAPI through YFP to Cy5.
The white light pE-400 Illumination System enables optimised illumination at the touch of a button. It brings a new level of efficiency to applications such as fluorescence screening or sample visualisation on confocal setups, making the inconvenience of lamps a thing of the past.
Protecting your samples
Tight hardware synchronisation not only increases temporal resolution, but also means samples are exposed only during acquisition, protecting against photobleaching and phototoxicity and pushing the boundaries of time-lapse studies.
Live samples can be further protected by balancing the irradiance to the lowest level possible while still maintaining image quality, with control in 1% steps up to 100%. And the more life-like a cell behaves, the more valuable a data set becomes.
Capturing dynamic events is possible with the highest temporal resolution even without software, thanks to precise hardware synchronisation via global TTL input (>10µs) and compatibility with the pE-6501 (USB controlled TTL trigger box). This also enables seamless integration into compatible third-party imaging software such as Evident cellSens.
Intuitive global control
Global control of the white light on/off and irradiance is achieved through the manual control pod for quick and simple operation. For more complex experiments, global control is also possible with third-party imaging software such as µManager (via USB Type B connection).
The compact pE-400 Illumination System builds on award-winning CoolLED technology, with stable and reliable performance and ultra-low power consumption. The sustainability benefits go beyond energy efficiency, and by removing the need for toxic mercury, the pE-400 is a natural choice for cleaner, greener labs.
Fit to your microscope
The compact pE-400 is compatible with the majority of microscope models, with two light delivery configurations available: direct fit and liquid light guide.
Direct fit variants achieve higher irradiance by directly connecting to the microscope via dedicated microscope adaptors, with a simple once-only adjustment optimising the optical path of the microscope. Not only do these variants avoid extra loss of irradiance as the liquid light guide degrades over time, but they are also more cost-effective. This is because they avoid the need to replace the liquid light guide when it comes to the end of its life.
If there is a requirement to keep the source of illumination remote from the microscope, liquid light guide variants are available. These require a fixed 3 mm diameter liquid light guide, and an optional pE-Universal Collimator can be specified in conjunction with a microscope adaptor if required.

We are often asked about the power, intensity or irradiance of CoolLED Illumination Systems. The answer is not as simple as you might believe from many websites and data sheets, and it can be difficult to compare data from these sources as measuring set ups differ.
Photons are also lost as light travels from the light source to sample plane. The only way to objectively compare light sources is by measuring irradiance at the sample plane. To understand why we use the term irradiance and how to measure and compare light sources with accuracy and precision, download our white paper. Or please contact us if you have further questions.

The scientific community is driving change across academia, industry and government to make laboratories more sustainable. When it comes to fluorescence microscopy illumination, switching to the pE-400 Series can help laboratories meet their sustainability targets, by consuming less energy and avoiding the use of toxic mercury.
“It’s great to see how My Green Labs and CoolLED are helping to move things ahead in the area of laboratory sustainability”. – Todd Lynch, UCLA Capital Programs
The Cy5 (635 nm) LED in the pE-400 Series is a game changer and they also offer massively improved YFP excitation too. They are fantastic products!

We are working to fully integrate the pE-400 into all major third party imaging software programs, but in the meantime you can use the pE-6501 USB controlled TTL trigger box for software control.
The CoolLED pE Driver is first required for software integration, and can be downloaded here.
