X-Cite Fluorescence LED Illuminators

Excelitas proudly serves the needs of its customers in various sectors as a leading figure in the design and manufacture of LED light sources for fluorescence microscopy applications. For over 20 years, Excelitas has been a trusted partner of researchers through X-Cite Illuminators, our leading brand and the undisputed leader in fluorescence illumination.  

X-Cite offers a wide range of lamps and LED light sources that are compatible with major microscope brands and provide high-power fluorescence excitation. These LED illumination solutions are easy to use, with no bulbs to install or replace, and feature intuitive controls, making them easier to install and operate, and an environmentally friendly alternative to mercury lamps.  

Backed by a reputation for quality and excellent customer service, you can trust Excelitas to provide unmatched illumination solutions that suit a wide range of applications.

Fluorescence microscopy is a standard technique used in most laboratories around the world in almost every area of scientific research. For decades, researchers relied on the conventional direct-current gas discharge HBO^® mercury short-arc lamp as their go-to light source.  

These were later replaced by pre-aligned lamps, which were more advantageous as they contained less mercury, had longer lifetimes, and operated under a similar spectrum to mercury arc lamps but were considerably easier to install. 

Over time, researchers have come to rely on LED light sources for fluorescence microscopy due to their powerful optical output, intuitive controls, and no need to stock or install mercury bulbs. These LED light sources are beneficial in microscopy and imaging because they consume less energy, require less maintenance, have higher signal-to-noise (S/N) ratio, offer instant on/off control, and require fewer replacement parts overall. 

Excelitas is the undisputed leader in fluorescence illumination systems with our X-Cite LED family. Our comprehensive illumination solutions are ideal for a wide range of microscopy applications. These range from broad-spectrum LED light sources for absolutely any fluorescence microscopy, to advanced high-end multi-color illuminators with intelligent pulsing and triggering capabilities.

It comes with four configuration options as well as pre-installed clean-up filters to equip researchers with illuminating systems that are well-suited for their existing and future imaging needs. 

• X-Cite mini+ Compact, LED Illumination System - for various routine fluorescence imaging applications, the X-Cite mini+^® is the perfect solution. It offers a high-powered performance while coming in a compact package and at a reasonable price. Two UV models are available at 365 and 385 nm to give labs the flexibility to work with their chosen or preferred DAPI filter sets.  

• X-Cite XYLIS II Broad Spectrum LED Illumination System - the XYLIS™II comes with X-Cite’s award-winning LaserLED Hybrid Drive^® technology to overcome the LED green gap. It is designed to be a true arc lamp replacement for most applications requiring routine and advanced fluorescence imaging capabilities and has the broadest spectrum available in a white light LED to offer optimum brightness that rivals even traditional arc lamps. This is an excellent addition for labs looking to enjoy LED without compromising price, flexibility, or performance. 

• X-Cite 110LED Illumination System - for a more compact white LED light source, the 110LED offers exceptional field uniformity and performance. It provides excitation for various lab imaging applications, such as GFP, DAPI, Cy5, and mCherry routine imaging. It comes with manual, PC, and TTL control, which guarantees 25,000 hours of operation without requiring bulb, lamp, or module replacement. 

• X-Cite XLED1 Multi-Triggering LED Illumination System - for high-power LED light sources, the XLED1 offers optimal performance. It is designed to optimize fluorophore excitation with unmatched LED switching speeds. What makes this device unique is its plug-and-play modularity, which allows the system to evolve depending on its research applications, allowing its LED modules to interchange
