Abstract

An optical head for an endoscope is fitted with an imaging system comprising a solid state imaging sensor and with an illuminating system comprising illuminating means, e.g. LED's. At least one illuminating means is defined by a parameter, which value is different from the value of the same parameter of the remaining illuminating means. Among the parameters are luminous intensity, luminous intensity distribution angle, and direction of the longitudinal axis of the illuminating means.
