Abstract
An x-ray imaging device can include an x-ray detector and an optical-blocking filter. The x-ray detector has an entrance-window surface for receiving x-rays, at least one side surface, and a back surface facing in an opposite direction from the entrance-window surface. The optical-blocking filter is deposited on and fully covers at least the entrance-window surface and the side surface of the x-ray detector, wherein the optical-blocking filter blocks visible, ultraviolet, and near-infrared light.
