About CoolLED Microscope Illumination
CoolLED develops high-performance LED illumination systems for microscopy, including fluorescence imaging, transmitted-light microscopy, calcium imaging, optogenetics and advanced research applications.
Modern LED illumination provides a practical alternative to traditional mercury and metal-halide microscope light sources. Benefits can include precise electronic control, rapid switching, stable illumination, long operating life and reduced energy consumption.
CoolLED systems can be configured for a wide range of microscope platforms using direct-fit arrangements, liquid light guides, fibres, collimators and microscope-specific adaptors.

Why Upgrade to LED Microscope Illumination?
LED illumination provides a modern alternative to traditional mercury and metal-halide microscope illuminators and can offer important practical, technical and environmental advantages.
Instant Control
LEDs can be switched electronically without the warm-up and cool-down behaviour associated with traditional arc lamps.
Stable Illumination
Consistent LED output supports repeatable microscope imaging and quantitative workflows.
Long Operating Life
LED technology reduces dependence on frequently replaced arc-lamp bulbs and associated alignment procedures.
Lower Energy Use
LED illumination can reduce power consumption compared with traditional mercury-based illumination systems.
Mercury-Free Microscope Illumination
Laboratories are increasingly moving away from traditional mercury-based fluorescence illumination towards LED technology.
CoolLED illumination removes the requirement for mercury arc lamps while offering long operating life, controllable output and reduced energy consumption.
Auckland Scientific can help laboratories assess existing fluorescence microscope illumination and identify appropriate CoolLED upgrade options.
Why Buy CoolLED from Auckland Scientific?
Correct fluorescence illumination depends on more than simply choosing a light source. The microscope, filter sets, fluorophores, objectives and imaging requirements all need to work together.

CoolLED Distributor in Bishop Auckland & North East England
Looking for CoolLED microscope illumination in the North East? Auckland Scientific is based in Bishop Auckland, County Durham and supplies CoolLED LED illumination systems to microscopy customers throughout County Durham, Newcastle, Sunderland, Teesside, Northumberland and North East England.
We also supply and support CoolLED customers throughout the United Kingdom.
Tell us which microscope you have, your fluorescence filter sets or fluorophores and what you are trying to achieve, and we can help identify a suitable illumination configuration.
CoolLED Technical Resources
Access CoolLED product information, manuals and technical resources through the Auckland Scientific Technical Resource Centre.
Which CoolLED System Do I Need?
The appropriate CoolLED system depends on the microscopy technique, wavelengths required, fluorophores, filter sets, microscope model, light delivery method and the level of control required.
A routine fluorescence microscope may require a very different illumination configuration from a multi-channel live-cell imaging, calcium-imaging or optogenetics system.
If you send us details of your microscope, current light source, fluorescence filter cubes and application, Auckland Scientific can help determine which CoolLED system and accessories are appropriate.
