High Power, Broad-Spectrum LED solution for Fluorescence Microscopy
The X-Cite® 120LED brings a whole new perspective to LED illumination with no
compromise. The 120LED offers superior optical power and exceptional
field uniformity at the specimen level with the broadest spectrum of fluorescence illumination through manual, PC and TTL control.
With LEDs guaranteed for 25,000 hours and no lamps or modules to replace, X-Cite
120LED offers sheer simplicity and convenience to researchers allowing
them to focus on their experiments instead of equipment maintenance.
"The X-Cite 120LED provides accurate FRET measurements and works well with all of our
fluorophores. We find it bright, uniform and easy to use."
Dr. Ammasi Periasamy,
W.M. Keck Center for Cellular Imaging,University of Virginia, USA
"The X-Cite 120LED is bright and stable and our users love it! It saves us time and energy by eliminating the need for
lamp changes and alignment that were required with our old HBO systems."
Dr Dongsheng Wu,
Queen Mary University London, UK

High Power, Broad-Spectrum LED Solution for Fluorescence Microscopy
The X-Cite 120LED microscope light source is designed for optimal imaging and data reliability, providing superior illumination uniformity with maximum stability over
time. The X-Cite 120LED provides broad-spectrum excitation (370-700nm) with high-powered optical output.
Benefits of LED Microscope Illuminators
LED microscope illuminators are an excellent choice of a microscope light source due to their ability to provide instant illumination and at full
intensity as soon as they are turned on, as well as having outstanding temporal and spatial stability. In contrast, incandescent and arc lamps require
a significant warm-up period for the temperature of the lamp and the intensity of illumination to stabilize. This stabilization period, which can be up
to an hour for some lamps, is required in order to ensure the illumination intensity remains consistent for the gathering of time-lapsed video segments
and reproducible measurements. The stabilization period of LED microscope light sources like the X-Cite 120LED lasts merely a few microseconds, which
saves on electricity, reduces delays prior to data collection, and allows more efficient use of microscope systems.
Another benefit of LED light sources for fluorescence illumination is that they can be turned on or off as often as required with no effects on their
impressive longevity. The LEDs in the X-Cite 120LED are guaranteed for three years (25,000 hours) with ultrafast shuttering capability. This feature is
particularly important for protecting specimens in live cell imaging, where overexposure to light can cause phototoxicity or photobleaching of the
fluorescent protein or dye. Precise management of the light intensity and the X-Cite 120LED’s on/off response times of 1ms or less provide the control
needed to protect live cells.
Features of the X-Cite 120LED Microscope Light Source
The X-Cite product family of illumination systems is designed specifically for fluorescence microscopy. The thermal management of the X-Cite 120LED
is innovatively designed to allow direct coupling between the microscope light source and the microscope for maximum optical power without additional vibration.
With the X-Cite 120LED, there are no bulbs or modules to install. The LEDs in the microscope light source are rated to 25,000 hours, and there are no consumable components. Over the lifetime of the microscope illuminator, this translates into cost savings on replacement bulbs, light guides, and reduced microscope downtime. Therefore, researchers can focus on their experiments rather than on equipment maintenance. The X-Cite 120LED raises the bar for convenience and ease in fluorescence excitation.
Multiple control options are available for the X-Cite 120LED, making it suitable for any fluorescence illumination set-up. For multi-day time-lapse experiments, the X-Cite 120LED can be fully automated, yet it can also be controlled with an intuitive and ergonomic manual SpeedDIAL. When connecting the X-Cite 120LED to a PC or triggering via TTL, LED on/off response times as short as 50µs can be achieved.
The X-Cite 120LED is the perfect mercury-free option for most fluorescence imaging applications. The X-Cite 120LED’s microscope light source delivers broad-spectrum, high-power fluorescence excitation from 370-700nm, which is applicable to a wide variety of commonly used fluorophores and fluorescent proteins. Superbly engineered direct coupling optics guarantee a bright, uniform microscope light source for microscopes from all major manufacturers.
