Certain embodiments include medical devices for capturing images of a localized portion of a body, such as the eye or skin tissue. An exemplary system utilizes a hand-held portable viewer. Various embodiments of the viewer have telecentric optics with a focal length of between about six inches and about twelve inches. The viewer also includes an image sensor adapted to capture an image of the object being studied, and may include one or more illumination sources selectively operable to illuminate the object. A light meter that measures a light level reflected from the object and a level that measures a rotational position of the viewer relative to a reference level position may be included. One or more filters may be removably fastenable to the viewer to cover the illumination source or sources and/or the aperture. |
