According to one embodiment, a light box for use with a dental intraoral camera is disclosed. The light box having a lamp inside is coupled to the dental intraoral camera via fiber optic cables. The light box allows easy access to the lamp for lamp replacement by pulling a tray out containing the lamp.

Easy access light box

A focus mechanism having an actuator positioned near the rear of a handheld piece and that allows a lens element to be moved with respect to a stationary image sensor to achieve a range of focus. When implemented as a manual focusing feature of an intraoral dental camera or handpiece, the focus mechanism allows greater control of focus as the user's hand that grasps the actuator (e.g., ring) is not in close proximity to the distal end of the camera which is inserted into the patient's mouth. Maintaining the image sensor stationary also helps increase system reliability. In a particular embodiment, a variable profile cam allows high precision focus with the camera inside the patient's mouth, while still allowing enough focus travel for capturing a head shot or an image of the patient's smile or face when the camera is moved outside the patient's mouth.
