How does one choose a microscope light source?
Selecting a fluorescence microscope light source depends on the application. How fast are you acquiring images? How much intensity control do you need for your light source? How fast do you need to shutter the light? Find out which system is most suitable for your application – CONTACT US today!
X-Cite® offers a wide selection of illumination systems to meet your application needs ranging from the X-Cite® 120Q best used for routine fluorescence imaging and the X-Cite® 120PC for shuttered illumination through several software applications; the X-Cite® 200DC is suitable for short-exposure imaging and the X-Cite® exacte for long-term stability and time-lapse studies. Our LED suite features the X-Cite® XLED1 with intelligent triggering and pulsing capabilities to extend live-cell imaging and the NEW X-Cite® 120LED as a green alternative to the X-Cite® 120Q.
Power Measurement in Fluorescence Imaging
The X-Cite® Power Measurement System measures optical power where it matters most — at the objective plane. With consistent illumination levels, reproducible imaging results can be ensured while increasing the integrity of your research. Whether you use a lamp, LED or laser, the X-Cite® power meter can measure light intensity from a light guide or at the end of a specific objective.
In the case of lasers, they are notorious for drifting and a nanometer drift in optics can result in a major decrease in the power of the light reaching your sample. To see an example of how the X-Cite® Power Meter can work to help maintain your fluorescence microscopy system and reduce equipment down-time, see the following case study.
