Omicron ledHUB light engine

Key features of the LedHUB®:

- Modular principle for up to 6 different wavelengths with user-upgradability
- Individual analogue modulation inputs for fast power control of LED wavelengths
- User replaceable excitation filters (bandpass filters) for each LED channel
- Precise intensity control in 0.1% steps (0-100%) by computer control (USB)
- Individual digital modulation inputs for fast full on/off control with <2µs switching time
- Intelligent SYNC in- and outputs for master or slave control of/from external cameras or instruments
- Stable & repeatable – TEC temperature controlled LED chips for reliable and consistent results
- Compatible to 2, 3 and 5mm Liquid Light Guides and SMA or FC/PC connectorized quartz fibres
- Excellent uniformity over field of view – fixed and stable, no alignment necessary
- Long lifetime – expected to exceed 25,000 hours of operating time

The Omicron LedHUB is a high power LED light source for Biotech, industrial and analytical applications. With up to 6 different wavelengths between 365 and 840nm, it can be used in applications like widefield microscopy, optogenetics, chemical analysis, forensics to name but a few. The modular principle of the LedHUB® provides the possibility to start with only one or two wavelengths initially and user-upgrade 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.
