Illumination system comprising an optical waveguide with a diffuser element, and method for producing and/or at least structuring a diffuser base body partially or in sections

Abstract

The invention relates to an illumination system (1), particularly for a medical treatment and / or diagnosis system, comprising at least one laser light source (10), and an optical waveguide (30) that,on its proximal end, can be connected to and / or associated with the at least one laser light source (10), and, on its distal end, comprises a diffuser element (40) with a longitudinal axis extending perpendicularly to the coupling surface of the optical waveguide into the diffuser element, said diffuser element irradiating light over the active length (40.2) thereof laterally to the longitudinal axis, during the operating state thereof, and said diffuser element (40) comprising at least one diffuser base body (43) containing at least one scattering element (43.6), said at least one scatteringelement (43.6) being oriented along the longitudinal axis (43.2) of the diffuser base body (43) substantially parallel thereto, or arranged at an angle to the longitudinal axis. Devices for homogenising the irradiation intensity along the longitudinal axis (43.2) of the diffuser base body (43) are provided on the distal end of the diffuser base body (43) and / or surrounding the transition region between the optical waveguide (30) and the diffuser base body (43) and / or the diffuser base body (43) itself, at least partially or in sections. During the operating state, the intensity distribution ofthe lateral irradiation of the illumination system deviates by a maximum of + / - 50%, preferably a maximum of + / - 30% and most preferably a maximum of + / - 5% from the mean lateral irradiation intensity. The invention also relates to a method for producing and / or structuring a diffuser base body (43) at least partially or in sections.

Description

technical field [0001] The invention relates to an illumination system, in particular for a medical and / or diagnostic system, and to a method for producing a diffuser matrix, in particular for an illumination system, and to a method for A method for at least partially or sectionally forming a diffuser base body, in particular for adjusting the intensity distribution of the lateral emission. Background technique [0002] Such irradiation systems are increasingly used in the medical field. The current main application areas can be classified as: [0003] Photodynamic therapy (PDT) for tumor treatment; [0004] · Venous laser therapy (EVLT) for the treatment of varicose veins; [0005] Laser-induced interstitial thermotherapy (LITT); and [0006] • Other applications, eg in the field of dentistry, ophthalmology and dermatology. [0007] Photodynamic therapy (PDT) is a minimally invasive treatment option for a variety of cancers. PDT is a procedure that uses light in combi...

Problems solved by technology

In addition to their complex introduction being difficult to control (e.g. in terms of distribution and / or size of the aforementioned nanocracks or nanovoids), nanocracks or nanovoids can also have a negative impact on the breakability of the component

In addition, in all methods, it has to be expected that the required uniformity of lateral emission will not be achieved due to the exponential decay of the lateral emission in the case of a sufficiently uniform design or due to inhomogeneous distribution
