TETE OPTIQUE BISPECTRALE A USAGE UNIQUE POUR VIDEOENDOSCOPE ET VIDEOENDOSCOPE ASSOCIE

摘要

The head (1) has an illumination unit (41) e.g. optical fiber, to emit a monochromatic light with preset wavelength. Optical filtering unit formed of notch filter (6) and dichroic filter filters the wavelength in a narrow spectral band. The filtering unit filters an image formed by a lens (3) on a micro camera (11). Electrical/optical connectors (31-33) are connected to a white light illumination unit (40), the illumination unit and the sensor and respectively coupled with a power supply unit (21) and image exploitation system (22) of a video endoscope. The white light illumination unit includes a light source i.e. organic LED. An independent claim is also included for a video endoscope.
