Abstract
An environmental enclosure provides a maintenance free surfaceless viewing window through a specially designed aperture for a clean, clear field of view for the lens of an enclosed camera, as well as cooling and isolation from ambient and camera-generated temperatures. The environmental enclosure device utilizes a method of pressurizing the environmental internal to the device to create a positive air flow through the aperture. The aperture is designed to create a vortex in order to encourage a surfaceless barrier which prevents external contaminants from entering the device. The aperture is provided through a removable aperture plate for ease in maintenance. The device provides unabated camera access through a removable portion which is angularly split from a fixed portion of the device, wherein the angular split permits the removal of the sufficient portion of the device in a tight-fitting region.
