Abstract
A dental video camera includes a housing which has an elongated cavity with a distal end and a proximal end, an adjustably focusing lens, a CCD camera system which is disposed within the elongated cavity of the housing, a fixed focusing lens system and an electrically adjustable iris. The adjustably focusing lens provides a focusing adjustment between a near field o:f focus and a far field of focus. The CCD camera system is optically coupled to the adjustably focusing lens and and is disposed in the elongated cavity of the housing adjacent to the distal end thereof. The electrically adjustable iris is optically coupled to the adjustably focusing lens and CCD camera system. The adjustable iris is adjusted between a nearly closed opening and a wide open opening in response to the focusing adjustment between the near field of focus and the far field of focus.
