CoolLED pE-300 White

Designed to offer broad-spectrum LED illumination for general use in fluorescence applications

A compact and simple to use LED illumination unit, roviding a broad spectrum of illumination, covering the excitation bands of common fluorescent stains. Operation is by a remote manual control pod with instant on/off and intensity control from 0-100%. Remote control is available via USB or TTL trigger.

Enhanced spectrum

As part of the pE-300 Series, the NEW Enhanced pE-300white now delivers DOUBLE the intensity at the microscope sample plane. 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.

As a replacement to a metal halide source on a confocal microscope, the liquid light guide configuration is particularly suitable for pre-aligning samples before scanning commences. In this way, photo bleaching of the sample can be minimised when LED illumination is used.

Control pod for operation and access to settings and usage history


Manual control for instant on/off and intensity control in 1% steps from 0 – 100%

Individual bands can be selected/deselected and controlled independently as desired


Via single TTL for on/off control of selected channels using a BNC connection on the light source.

Triggering speed <20us

USB control
