Image-acquisition device and method of fabricating the same |
摘要 |
Provided is an image-acquisition device including an image acquisition element; a prism that is secured to the image-acquisition element and that has an entrance surface through which light enters from a direction that intersects an optical axis of the image-acquisition element, an exit surface that is substantially parallel to an image-acquisition surface of the image-acquisition element, and a reflection surface that deflects the light that has entered through the entrance surface toward a direction that is parallel to the optical axis of the image-acquisition element; and a cover member that is secured at a position that covers the reflection surface of the prism and that has an outer surface that is substantially parallel to the image-acquisition surface, wherein an end surface of the cover member closer to the entrance surface is disposed at a position protruding beyond the entrance surface. |

1. An image-acquisition device comprising:
an image-acquisition element; a prism that is secured to the image-acquisition element and that has an entrance surface through which light enters from a direction that intersects an optical axis of the image-acquisition element, an exit surface that is substantially parallel to an image-acquisition surface of the image-acquisition element, and a reflection surface that deflects the light that has entered through the entrance surface toward a direction that is parallel to the optical axis of the image-acquisition element; and a cover member that is secured at a position that covers the reflection surface of the prism and that has an outer surface that is substantially parallel to the image-acquisition surface, wherein an end surface of the cover member closer to the entrance surface is disposed at a position protruding beyond the entrance surface, and wherein the exit surface of the prism is in direct surface contact with the image-acquisition element. |
