Abstract
Improved fluoresced imaging (FI) endoscope devices and systems are provided to enhance use of endoscopes with FI and visible light capabilities. An endoscope device is provided for endoscopy imaging in a white light and a fluoresced light mode. A chromatic adjustment assembly, typically implemented with prisms, compensates for a chromatic focal difference between the white light image and the fluoresced light image caused by the dispersive properties of the optical materials or optical design employed in the construction of the optical channel. The assembly is placed optically between the most proximal rod lens of the endoscope and the focusing optics, typically at an internal telecentric image space, to improve the chromatic correction. The prism assembly directs incoming light with different spectral content along separate paths which compensate for chromatic aberration.
