April 6, 2011 (Southbridge, MA) – The 2nd generation of SCHOTT’s LED light engine (LEDgine™) platform now offers twice as much light as before. Specifically developed for more efficient coupling of LED light into fiber optic bundles, it ideally illuminates active diameters from 3.0 to 6.0 mm. This makes the LEDgine™ optics module an excellent choice for medical applications, where small diameter light guides are commonly used.

The encapsulated LEDgine™ optics module that contains LEDs and focusing optics now features an integrated fan that ensures optimum cooling for a long lifetime. The even smaller footprint of the module allows easier integration into end-users systems, thanks to customized coupling adapters.

The light engine is made up of white High Brightness LEDs, which are focused onto the input of the light guide by specially developed focusing optics (patent pending). The high efficiency of the coupling system generates an extremely intense and homogeneous spot of light.

The separate control electronics have been optimized to lower energy consumption and enable portability when used with rechargeable batteries. It monitors the LEDs on the circuit board for over-temperature to ensure that the system remains functional for a long time. The external triggering option can be utilized to make fast movements visible. Driven by constant current, the light intensity of the LEDs can be continuously dimmed between 0 and 100%.

For applications that require the use of an additional filter to cut off a particular wavelength (i.e. for ophthalmic applications), a light guide adapter with integrated filter slider can be mounted onto the optics module. A customized flange for light guide coupling can be mounted to the front plane.
