Abstract

See full text

The invention concerns an optical system, and a video endoscope therefor, with at least one electronic active pixel image sensor with a progressive offset micro-lens array, and a lens system with a plurality of lenses in order to receive image light from an object field and direct it to the image sensor. The optical system has at least one interference filter coating located within the optical system, such that the angle of incidence of the image light on the filter coating is minimized, minimizing thereby the filtration characteristics of the coating that are angularly dependent. This minimization improves the reliability of fluorescence imaging with short optical systems. The location for the filter coating may be on a curved surface, such as a lens, or on a properly positioned flat element within the optical system.
