Device for detecting tumorous tissue, has objective suitable for processing ultraviolet light; images are generated from two different spectral regions of fluorescing object field

摘要

The device has a stimulation light source(s) emitting a wavelength of between 300-314 nm, a light conductor(s) carrying the light to an object field, an objective(s) forming an image of an autofluorescence and/or remission signal on a camera chip and a data processing system(s). The objective is suitable for processing ultraviolet light and designed so images are generated from two different spectral regions of the fluorescing object field. The device has at least one stimulation light source (12) emitting a wavelength of between 300-314 nm, at least one light conductor (14) for carrying the light (34) to an object field (18), at least one objective (24) for forming an image of the autofluorescence signal and/or remission signal (20) generated with the light to a CCD or ICCD chip of a camera and at least one data processing system for processing signals from the camera. The objective is suitable for processing ultraviolet light and is designed so that at least two images are generated from two different spectral regions of the fluorescing object field, one in the ultraviolet range and one in another wavelength range of the autofluorescence signal and/or remission signal. Independent claims are also included for the following: a method of detecting tumorous tissue.
