pE-300^ultra

The pE-300^ultra is the most controllable member of the pE-300 Series for LED microscope lighting.  In addition to the many features of the pE-300^lite and the pE-300^white, the system offers precise control over wavelength irradiance and shuttering.  Until now these benefits have only been accessible to users of high end, highly flexible LED microscope illumination systems such as the CoolLED pE-4000.

It allows adjustment of output in 1% steps, giving precise control.  The broad spectrum covers everyday fluorophores: DAPI, CFP, Aqua, FITC, TRITC, TxRed, Cy5 and many more.

Direct fit or liquid light guide

There are two pE-300^ultra configuration options: direct fit or liquid light guide. The direct fit variant delivers higher irradiance and reduces the cost to buy and run thanks to fewer consumables.

For confocal microscopes, the liquid light guide variant offers the ideal replacement to a metal halide light source, minimising photobleaching and phototoxicity when viewing samples before scanning. More information on the available variants can be found under specifications.

Capturing high-speed events

The pE-300^ultra offers triggering from multiple TTL inputs which, coupled with the ability to mount inline excitation filters, provides microsecond switching of pre-filtered excitation light. When paired with today’s high performance multi-band filter sets, this facilitates imaging traditionally achieved using a white light source and a filter wheel, with all the benefits of LEDs – and most excitingly at speeds not previously so affordable. For live cell imaging applications, events can now be captured that might previously have been missed. Read our white paper to compare the benefits and trade-offs of different possible illumination configurations.

Fast multi-channel imaging

Fluorophores can be viewed either individually or in combination, without filter cube changes.  This makes the pE-300^ultra ideal for use with multi-band filter sets as the screening process can be simplified when fewer filter cubes are used.  Independent control of the three LED channels means that the user can control the level of excitation of each fluorophore independently on a multi-stained sample, potentially removing the need for single-band filter sets altogether.

Sequence runner for multi-channel excitation

It is now possible to run through a sequence of excitation channels using a camera or other external hardware which has only a single TTL-out, thanks to the Sequence Runner mode. Complex illumination protocols can now be run at high speeds and without the need specialised and costly hardware. The order of each fluorophore to be captured is defined via the simple Control Pod, with the pE-300^ultra Light Source accepting a single TTL output from the experiment set-up’s camera to initiate the step-through of a sequence of excitation channels.  This feature is independent of the individual channel TTL inputs on the Light Source. Find out more about this useful feature in our Sequence Runner tutorial video.

Energy efficiency for cost-saving sustainability

When it comes to making labs safer and more sustainable, LED microscope lighting is an attractive option when compared to old toxic mercury or metal halide lamps. All three channels of the pE-300^ultra at full power use just 60 Watts, which is even lower than other LED technology which uses 120 to 350 Watts. “Green Grants” are even sometimes available from establishments, providing financial support owing to the reduction in institutional energy usage.

Award winning technology

CoolLED’s pE-300 Series was the 2017 winner of the International Institute for Sustainable Laboratories (I2SL) “Go Beyond Award” for “Excellence in sustainability in laboratory and other high technology facilities”.

The pE-300^ultra offers:-

• Clean bright illumination across the spectrum – excites common fluorescent stains
• Specify for  existing single and multi-band filter sets – no need to buy new filters
• Instant on/off – No shutters required, no warm up or cool down
• Simple to fit, simple to use – no alignment, a once only adjustment
• Stable & repeatable – reliable and consistent results
• Wide range of microscope adaptors – fits most microscopes
• Precise irradiance control in 1% steps (0-100%) – no ND filters required
• Excellent uniformity over field of view – fixed and stable, no alignment necessary
• Long lifetime
• Removable inline excitation filter holders – no moving parts
• Individual channel triggering via TTL in microseconds
• Sequence Runner – sequenced excitation from a single TTL-out

The system comprises a pE-300^ultra Light Source, Control Pod, set of three Excitation Filter Holders and Power Supply.

Choosing configurations

There are two pE-300^ultra configuration options:

Direct Fit: Higher irradiance is possible when directly connecting to a microscope. Select 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: If there is a need to keep the source of illumination remote from the microscope, the Liquid Light Guide variant is available for use with a 3 mm diameter Liquid Light Guide.  An optional pE-Universal Collimator and microscope adaptor can also be selected. We now include a Light Source stand for the pE-300^ultra Illumination Systems ordered for light guide delivery.

Choose single-band or multi-band variant

DAPI can be excited at either 365 nm or 400 nm and microscopes typically have a filter set which allows one or other of these wavelengths to be transmitted.  To accommodate this, the pE-300^ultra can be specified in one of two waveband configurations to match existing filter sets within the microscope.

A microscope which is populated with a number of single band (“SB”) filter sets will typically have DAPI excitation at 365 nm and a microscope with multi-band (“MB”) filter(s) has excitation at 400 nm.  The user can specify the configuration which is appropriate for their microscope.

All data correct at time of publication

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.
