Abstract
A medical-endoscopic instrument includes a distal elongate insertion section (1), for the minimal-invasive introduction into a human or animal body, with a first LED (5), a second LED (7) and a picture sensor (9). The first LED includes a first light spectrum (19), suitable for fluorescence endoscopy. The second LED includes a second light spectrum (21), suitable for white light endoscopy. A light filter (23), arranged in front of the second LED in the viewing direction (x), has a transmission spectrum (25). The second LED is configured to irradiate according to the second light spectrum on average more intensively in a first wavelength region (K) than in a second wavelength region (L). The light filter is configured to let through light, which is emitted by the second LED, according to the transmission spectrum, on average less in the second wavelength region than in the first wavelength region.
