Advanced Techniques Using LED Illumination 

There is a whole range of newly emerging techniques that have traditionally employed laser light to illuminate a sample, but are now turning to LEDs. An example is structured illumination microscopy (SIM), a wide-field technique that can improve the lateral resolution...

Focus Drift Correction with LEDs

LEDs are not just used for illuminating a sample in time-lapse microscopy. They are also used in most focus drift correction systems (from manufacturers such as Leica, Nikon and Zeiss), which are feedback devices used to maintain focus. At high magnifications, the...
