ABSTRACT:
An endoscope with an eyepiece and an objective lens system used for observing an object in an environmental media. The distal most optical element in the objective lens system is a spherical lens. The spherical lens has a curved distal surface that contacts the environmental media. The objective lens system facilitates the control of the distortion in an image generated by the objective lens system to approximate a reverse distortion of the eyepiece system measured as the distortion in an image generated distally of the eyepiece system of an object positioned proximally of the eyepiece system.
