LedHUB Logo

The Omicron LedHUB is a high power LED light source for Biotech, industrial and analytical applications. With its up to 6 different wavelengths between 340 and 840nm it can be used in applications like widefield microscopy, Calcium Imaging, optogenetics, chemical analysis, forensics and many more. The modular principle of the LedHUB® provides the possibility to start with only one or two wavelengths initially and user-upgradeability to further wavelengths at a later stage. The capability of fast switching between the wavelengths and high speed analogue modulation of the intensity is a key feature for demanding applications.
