Thanks to its close collaboration with Luminus, PHOTONIC is one of the first partners worldwide to have access to the latest developments in LED light sources.

Today, surgeons can monitor tissue blood circulation in real time during operations and thus make more precise decisions. As a result, they can more easily determine lymphatic tissues, boundary lines when removing tumours or blood supply to the organs. These deep insights into the human body are made possible by fluorescence imaging, an area in which PHOTONIC has long years of experience and abundant expertise.

ADDED VALUE THANKS TO THE COLLABORATION WITH LUMINUS
PHOTONIC‘s collaboration with high-tech company Luminus delivers real added value for its customers. Luminus specialises in the manufacturing of powerful LEDs for different wavelengths, which stand out through their excellent light qualities. PHOTONIC Business Developer Stefan Preißer explains where these qualities lie by using the example of the CFT90-WDH LED: ”The compact, monolithic VIS LED stands out through its high light output and very good colour specifications, which remain constant throughout the active illuminated area, the solid angle and the lifetime of the LED. This is decisive when tissue needs to be illuminated as orthrochromatically as possible over a large visual field. Thanks to PHOTONIC‘s robust light module design, including a customised cooling solution, the device has an average lifetime (L70) of well over 30,000 hours. ”As a result of the cooperation with Luminus, we were one of the first companies worldwide to test these new LEDs and promptly integrate them into a newly developed module for serial production“, says Preißer. PHOTONIC also wants to be a step ahead with the new CFT50-X LED. ”The product is not yet available on the market but is already being tested by us for the first prototypes. In future, it will be used to illuminate smaller surfaces directly or through small endoscope diameters using a very powerful high-quality VIS light at an affordable price“, Preißer explains. At 5 mm2, the LED has a small active illuminated area and is therefore suitable for optical systems that require a high luminous flux with a smaller etendue. For higher requirements with regard to etendue or for very specific wavelengths with a narrow band, diode laser sources are used and incorporated in a system-integrated design.

Examples like these demonstrate that, from the system to optical design, mechanics and electronics through to thermal management, PHOTONIC implements the best possible solutions for the development and manufacturing of high-power light modules. Moreover, it achieves this quickly, with a focus on individual customer requirements and, on request, with end-of-line testing.
