Abstract
A veterinary otoscope permitting examination of an ear is defined by an instrument head including a proximal end and a distal insertion portion that is insertable into the ear. The veterinary otoscope includes an imaging lens train disposed within the instrument head, wherein each of the imagine lens train, an eyepiece and a distal opening of said insertion portion are aligned along an optical axis. The veterinary otoscope further includes a focusing mechanism for selectively moving at least one of the imagine lens train and the optics contained within the eyepiece relative to one another along the optical axis. The imagine lens train and the optics in the eyepiece define an optical system such that an entrance pipil is substantially located in the distal insertion portion of the instrument head, thereby enabling the entire tympanic membrane to be viewed at once by the user.
