Abstract: An image sensor assembly having a sensor window positioned in front of an image sensor, having structure and/or characteristics to prevent the formation of condensation on the sensor window. Structure to prevent the formation of condensation includes thin films which can have anti-condensation, anti-reflective, electrically conductive, and/or thermally conductive properties. The sensor window can further have a textured surface to displace water so as to avoid condensation formation on the window surface. The sensor window, and in some embodiments a frame, can be maintained at an elevated temperature proximate to the image sensor during operation to prevent the formation of condensation.
