Photonic showcases high-power LED modules at the LASER World of Photonics. The lighting specialist specifically adapts these to customer requirements so they may be integrated into any existing lighting system. This makes them attractive for both industrial and medical applications.

Bladder cancer is the fourth most frequent form of tumour disease among men. What makes this form of cancer particularly dangerous is the fact that the small and flat-growing carcinomas are extremely difficult to see during normal inspections using conventional white light. Fluorescence techniques, on the other hand, can make even the smallest changes in the bladder visible. Fluorescence diagnosis recently made a Quality leap with the F6000-M by Photonic. It is currently the brightest endoscopy module on the market.

“In combination with the cascadable current drivers for extremely high LED currents, the high-end cooling system and the optical light coupling, we managed to achieve light fluxes of over 2,300 lumens at the fibre optic output. This outshines even 300-watt xenon light sources”, explains Photonic Product Manager Christoph Cseko. As endoscopes are becoming increasingly thinner, the F6000-M also stands out with its high light density for small fibre diameters.

The particular strengths of the F6000-M as well as the F5000-M are in great demand both in medical and in industrial settings. Ultra-high speed cameras and 3D imaging systems used for analysing quick movements or material behaviour rely on extremely high luminous fluxes. “The frames are sometimes exposed only for a few microseconds. If too little light hits the object during this time frame, the image is useless.

On the other hand, if you extend the illumination interval, quick movements will appear blurred. Therefore, when coupling light in light guides, it is necessary to push the physical limit, the so-called etendue, to the extreme“, says Christoph Cseko.

The etendue implies that one cannot change beam size and angle of a light source independently of each other. Optics developers at Photonic are bringing both modules very close to this physical limit, thus offering customers the advantages of outstanding brightness and reliability. Customer-specific requirements such as, for example, synchronised flashing, a feature critical in Automation applications, can be quickly implemented on the basis of Photonic’s modules.

In the development of the F4000-M, Photonic focused on another important aspect: compact size. As a result, this all-rounder is predestined for small illumination areas. Its possible applications range from treatment units for ENT or dental clinics to portable cameras in industrial and medical endoscopy or installation in the Support arms of surgical microscopes. Depending on the configuration, their brightness is comparable to 150W halogen or 100W xenon lights sources and thus significantly higher than in existing systems of this size.

Modular setup

To properly highlight the various applications of ist systems, Photonic offers its customers a series of development and production services ranging from application consulting and system integration support to interface definition and front-end/back-end design. The technological substructure for customer-specific developments is a modular setup. The latter allows all LED modules by Photonic to be specifically adapted to customer requirements and be integrated into any existing lighting system. The company’s highly skilled developers in its optics, mechanics, software and electronics divisions are capable of delivering every bespoke solution.
