Abstract
According to one aspect, a visualization device may include an image sensor, a lens for focusing light onto the image sensor, a first end, a second end opposite the first end, a lateral wall surface extending between the first end and the second end, and a coating on the lateral wall surface. The coating may include at least one of an electrically-insulating layer and a light-blocking layer, and may be deposited on the lateral wall surface using, for example, physical vapor deposition (PVD).
