CoolLED designs and manufactures cutting edge LED illumination systems for researchers and clinicians using the latest LED technology. Since our team of four introduced the first commercially available LED illumination system in 2006, we have led the way in transforming light source technology for fluorescence microscopy. LEDs are now the system of choice because they are more stable, longer lasting, and offer a wealth of performance benefits compared to traditional mercury-based illuminators. The comprehensive CoolLED product range includes:

pE-800 8-channel system from CoolLEDpE-800 Series - True 8-channel control with industry-leading <7 µs TTL triggering has never been so affordable or easy to use. While the pE-800 is designed for everyday fluorescence, the pE-800fura  offers the most comprehensive system for calcium imaging and ratiometric applications.

pE-4000 LED Illumination System from CoolLEDpE-4000 – the universal LED Illumination System for research fluorescence, with extensive functionality and the broadest spectrum of illumination available from 16 selectable wavelengths.

Pe400 Series from CoolLEDpE-400 Series – A choice of two Illumination Systems for routine to advanced fluorescence, with four powerful LEDs offering broad spectral coverage. This includes the bright white pE-400 and highly controllable pE-400max.

pE-300 series Illumination Systems from CoolLEDpE-300 Series – Three Illumination Systems for everyday fluorescence microscopy, which offer intense, broad spectrum illumination covering the excitation bands of common fluorophores.





pE-340fura – Custom LED Illuminator for Fura-2 ratiometric calcium imaging, built on our pE-300 Series technology, which also supports everyday fluorescence microscopy.

pE-100 range of compact, simple-to-use, single wavelength illumination systems for screening fluorescence.

We also offer the pT-100 range for transmitted illumination applications including brightfield, darkfield, DIC, Dodt gradient contrast and phase contrast.

If you’re after something a little different, CoolLED technology is available in OEM and tailor-made configurations for manufacturers who wish to integrate stable, controllable LED illumination into their products.
