LED illumination means no mercury to dispose of and lower energy costs due to low power consumption and the precise control offered. With the new enhanced pE-300^ultra, all 3 channels at full power use just 46 Watts. That is almost a quadruple efficiency increase!

This compares to other LED technology that uses 120 to 350 Watts. This leap forward in technology makes LEDs more attractive when compared to old Mercury or Metal Halide technology. Where “green” funding is available, the reduction in institutional energy usage improves the return on investment.

CoolLED’s pE-300 Series was the 2017 winner of the “Go Beyond Award” in the “Products” category for “Excellence in sustainability in laboratory and other high technology facilities” The International Institute for Sustainable Laboratories (I2SL) runs a unique awards program honouring organisations, individuals, products,and projects that are advancing sustainable, high-performance facilities.

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. This, when paired with today’s high performance multi-band filter sets, facilitates imaging traditionally done using a white light source and a filter wheel, with all the benefits of LED, and most excitingly at speeds not previously so affordable.

The system comprises a pE-300^ultra Light Source, Control Pod, set of three Excitation Filter Holders and Power Supply. It can be specified with a microscope adaptor for direct fit configuration or with a 3mm diameter liquid light guide if there is a need to keep the source of illumination remote from the microscope. An optional pE-Universal Collimator and microscope adaptor can be selected for use with a liquid light guide.

A benefit of the pE-300^ultra is that stains can be viewed either individually or in combination, without filter cube changes. This makes it 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 fluorescent stain independently on a multi-stained sample, potentially removing the need for single band filter sets altogether. For further information on improved multi-stain testing, go to the Downloads tab.

An important additional feature of the pE-300^ultra is that it includes CoolLED’s “Sequence Runner” multiple channel excitation mode. Users can define the order of their fluorophore capture using their pE-300^ultra Control Pod, then the pE-300^ultra light source can accept 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. This offers users the facility to run through a sequence of excitation channels using a camera which has only a single TTL-out.

With an expected lifetime in excess of 25,000 on hours and a comprehensive range of microscope adaptors, the pE-300^ultra can be fitted to most current and older microscopes and operate for many years without aligning or replacing bulbs. The result is a safe, convenient illumination system without any additional operating costs.

There are two pE-300^ultra configuration options:

Direct-fit

for connecting to a microscopes – by selecting 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

with a fixed 3mm diameter, liquid light guide. An optional pE-Universal Collimator can be specified in conjunction with a microscope adaptor if required.

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 intensity control in 1% steps (0-100%) – no ND filters required

• Excellent uniformity over field of view – fixed and stable, no alignment necessary

• Long lifetime – expected to exceed 25,000 hours of operating time

• Removable inline excitation filter holders - no moving parts

• Individual channel triggering via TTL in microseconds

• Sequence Runner - sequenced excitation from a single TTL-out

DAPI can be excited at either 365nm or 400nm 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 with the user’s 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 365nm and a microscope with multi-band (“MB”) filter(s) has excitation at 400nm. The user can specify the configuration which is appropriate for their microscope.

Reviews

I have recently tested the pE-300ultra with the TTL and with the USB - Ardino board a short time ago and it works really well , I used it for 2 colour timelapse at 100Hz . The Micromanager team has done a great job with the Ardino integration.

We were very successful including the pE-300^ultra in our microscope building set that we use to teach the principles of microscopy to our students. It became so popular that we include the set now also in other microscopy courses.

Just started using our new CoolLED pE-300^ultra and it’s so easy to use. The light is very bright and our images look great! What’s more, we don’t need to worry about replacing the bulb! An excellent choice!
