Innovative LED High Power Light Source for UV

27 Jul 2017

The successful „LedHUB“ LED light engine produced by Laser- and LED specialist Omicron is now available down to 340nm

Omicron‘s innovative „LedHUB LED Light Engine“ represents a new form of LED light source for science and research. The high-performance system can be equipped with one to six LED modules of many different wavelengths between 340nm in the UV up to 940nm in the near IR and offers fast analogue intensity modulation with up to 200KHz and digital modulation with a switching time of <2µs for each channel. The individual LED modules can easily be exchanged and added by the user. Hence the system can be adapted to individual application requirements and is future-proof.

With a direct and active temperature control of the LED chips it is possible to keep the power level and the emission spectra of the LED chips stable. This feature guarantees reliable and repeatable results in the customer‘s applications. 

The light of the various high power LEDs is combined within the "LedHUB" by special optics and can be coupled efficiently into quartz glass fibres or liquid light guides.

LEDs with up to 5.000 milliwatt of optical output power can be used in the "LedHUB" systems. Through directly accessible filter holders, that can be equipped with 25mm standard filters, the emission of each single LED may additionally be adapted to the application. The modulation is possible via external modulation signals as well as by an internal programmable signal generator. A SYNC in- and output ensures the synchronization of / from external devices like cameras, microscopes or DAC cards.

Especially for microscopic applications like Calcium imaging with FURA-2 fluorophores, that require rapid toggling at 340nm and 385nm, the LedHUB is an ideal alternative to lamp based Monochromators or sources with slow filter wheels.

The device can be conveniently controlled via the integrated RS-232 and USB-2.0 interface, the included software „Omicron Control Center“ or third party software. Typical applications include microscopy, fluorescence analysis and the use as multispectral light source in forensics. 

The "LedHUB LED light engines" are offered with a manufacturer's warranty of three years.
