pE 800 LLG SQ


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. Versatile, intuitive and backed by CoolLED’s world-renowned support and a 36-month warranty, the pE-800 with liquid light guide delivery makes next generation LED illumination accessible to all.

pE 800 Spectrum Graph 72dpi
Mix & match with eight channels

Eight powerful and efficient LEDs offer broad spectral coverage from 365-740 nm for use with fluorophores ranging from DAPI to Cy7. The choice of fluorophore is no longer limited by the light source, and choosing the optimal set for each application has never been easier – even as requirements evolve over time.

All eight channels can be individually controlled, with each LED selected to perfectly match the selected fluorophores. Excitation filters with white light sources let through more unwanted light, and by matching the LED this improves the signal to noise ratio for contrast-rich images revealing finer details and more information.

Capture high-speed events

Industry-leading <7 µs TTL triggering is a breakthrough for live cell imaging. Capturing dynamic events is possible with the highest temporal resolution and even without software, thanks to precise hardware synchronisation via TTL input for each channel and compatibility with the pE-6501-8  (USB controlled TTL Conversion Kit).

TTL triggering graph

The ability to fit inline excitation filters capitalises on TTL trigger speeds, as single-band excitation filters can be installed for each channel. When used alongside multi-band filters, for example in a Pinkel configuration, this removes the need for expensive external filter wheels and overcomes the latency restrictions of mechanical movement, presenting a low-cost approach to high-speed imaging.

Affordable automation with Sequence Runner

The popular Sequence Runner program takes speed one step further and combines the versatility of software with the <7 µs speeds of TTL, with minimal requirement for expensive electronic hardware. Once an LED and irradiance sequence are specified in software, Sequence Runner provides lightning fast synchronised triggering via the global TTL-in of the pE-800 and a single TTL-out from a camera (or other hardware).

The pE-800 is unique in offering the only 8-channel Sequence Runner available, and when combined with inline filters, transforms a manual microscope into an affordable and powerful eight-channel automated imaging system. As laboratory budgets become stretched, the pE-800 presents the ideal cost-effective Illumination System which makes high-end LED technology more accessible to life science researchers.

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.

In the Lightbridge graphical user interface (see below), live samples can be further protected by balancing the irradiance to the lowest level possible while still maintaining image quality, with fine (0,1 %) control from 0-2 %, and in 1 % steps up to 100 %. And the more life-like a cell behaves, the more valuable a data set becomes.

Intuitive software control

Software control is achieved through a fast USB 2.0 connection and the user-friendly LightBridge Graphical User Interface (GUI), where control options include:

Users can also benefit from full software integration in Nikon NIS Elements.

Beyond imaging

Eight individual analogue inputs allow irradiance to be controlled from 0-100 % for each channel via analogue signal (0-10 v), which is ideal for electrophysiology and optogenetics applications.

Fit to your microscope

The compact system is compatible with the majority of microscope models. Liquid light guide delivery offers flexible placement.

Sustainable illumination

The compact pE-800 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-800 is a natural choice for cleaner, greener labs.

Graphical user interface (GUI)

CoolLED LightBridge GUI operates via USB to allow:

  • On/off control
  • LED selection
  • Real time irradiance control
  • Sequence Runner
  • Save and load pre-sets
  • pE-800 start-up settings
  • Analogue settings

Triggering speeds dependent on individual PC operating system.

TTL & analogue
8 TTL inputs allow independent on/off control of each channel
8 analogue inputs 0-10 V, 0-50 kHz for dynamic control of irradiance from external analogue signals Global TTL for on/off synchronisation to camera
Triggering speed <7 µs

Sequence Runner
Combining software control with the speed of TTL, the Sequence Runner program allows LED sequences and irradiance to be programmed via LightBridge. The sequences are controlled via global TTL from a single TTL input such as from a camera TTL out or other external hardware, and therefore requires minimal electronic hardware.

USB 2 for PC connection. All other TTL and analogue inputs via BNC or SMB.

Light delivery

Light delivery via the standard 3 mm liquid light guide keeps the source of illumination remote from the microscope.  An optional pE-Universal Collimator and microscope adaptor can also be selected.

Choose 365 nm or 400 nm variant for UV

For optimum DAPI excitation, the pE-800 is available with a 365 nm or 400 nm LED for compatibility with existing filter sets. Find out more in our tutorial video here.
