High Power, Broad-Spectrum LED Solution for Fluorescence Microscopy
The X-Cite 120LED microscope light source is the newest addition to the X-Cite fluorescence illumination product family. As with all X-Cite products, the 120LED 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 120LEDs 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 theX-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, theX-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 50Ķs can be achieved.
The X-Cite 120LED is the perfect mercury-free option for most fluorescenceimaging applications. The X-Cite 120LED 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.
