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).
Claims18
A method of coating a visualization device, comprising:
- providing a masking material to a first end of the visualization device;
- providing the masking material to a second end of the visualization device;
- depositing a coating on the visualization device, wherein the coating includes at least one of an electrically-insulating layer and a light-blocking layer, wherein the coating is deposited on the visualization device using physical vapor deposition (PVD) that comprises sputtering titanium within a PVD chamber;
- securing the visualization device to a holding device by inserting the first end of the visualization device into a recess of the holding device in a first configuration or inserting the second end of the visualization device into the recess of the holding device in a second configuration before providing a masking material to the first or second ends of the visualization device or before depositing the coating on the visualization device;
- and
- removing the masking material, and portions of the coating on the masking material, from the first and second ends, while leaving the coating on a lateral wall surface of the visualization device that extends between the first and second ends.
A method of coating a visualization device, comprising:
- securing a plurality of visualization devices to a holding assembly, the holding assembly comprising a post having a first end, a second end, and a central longitudinal axis, a first member coupled to the post and engaging first ends of the plurality of visualization devices, the holding assembly further comprising a plurality of pins movable towards the first member to engage second ends of the plurality of visualization devices, leaving lateral wall surfaces extending between the first and second ends of the plurality of visualization devices exposed;
- and
- depositing a coating on the lateral wall surfaces of the plurality of visualization devices, wherein the coating includes an electrically-insulating layer and a light-blocking layer.
