The Perfect Light Sources for Image Splitters
In the fast-paced world of microscopy, having the right tools can make all the difference. At CoolLED, we’re dedicated to providing researchers with the most versatile, efficient, and stable LED microscope lighting available.
Our products are designed to meet the varied demands of modern microscopy, from routine imaging to advanced multi-channel fluorescence applications.

CoolLED: A Broad Range of LED Solutions
One area where our LED light sources really shine is in combination with image splitters. These devices are used to separate different channels or wavelengths of light emitted from the sample, allowing scientists to simultaneously capture multiple fluorescence signals.
Our broad range of LED systems are ideally suited for multi-channel imaging, making the most of image splitter technology.
Whether you’re looking for single-channel illumination or more complex, multi-channel setups, our LED light sources provide flexibility and precision for every task.
Some key features of our LED Illumination Systems include:
- Broad spectral range: From UV to red, our light sources cover the wavelengths necessary for the vast majority of fluorescence imaging techniques.
- Instant on/off control: Unlike traditional bulb light sources, our LEDs are ready to use instantly with no warm-up times, making them perfect for time-sensitive imaging. High speed control is also ideal for increased temporal resolution and minimised phototoxicity.
- Stable and flicker-free illumination: This stability is essential when capturing fluorescence signals, ensuring consistent, reproducible results.
- Energy efficiency: LEDs consume less power and produce less heat than traditional light sources.
With these advantages, our light sources provide the foundation for high-quality, reliable fluorescence imaging.
Image Splitters in Action
Image splitters are an essential tool in certain microscopy applications, especially some involving the use of multi-channel fluorescence imaging.
By splitting light into different channels, researchers can capture multiple signals in a single shot, saving time and improving efficiency.

- Live cell imaging: Time is critical when observing living cells. Image splitters allow you to capture several fluorescence markers simultaneously, preserving sample integrity and reducing the need for multiple exposures.
- FRET (Fluorescence Resonance Energy Transfer): This technique requires the detection of two fluorophores at different wavelengths. Image splitters, in combination with CoolLED light sources, make it possible to observe donor and acceptor fluorescence in real-time.
- High-throughput screening: In drug discovery and other large-scale experiments, image splitters help speed up the data collection process by capturing multiple fluorescence signals at once.
- Ratiometric imaging: For applications requiring measurement of ion concentrations (e.g., calcium or pH indicators), image splitters allow simultaneous capture of fluorescence signals at different wavelengths, improving accuracy.
- Quantitative fluorescence imaging: Researchers often need to measure fluorescence intensity from different channels. Using image splitters allows for more precise quantification by capturing these signals simultaneously, reducing potential variations caused by sample drift or light source instability.
