Abstract
Systems and methods are disclosed that provide an infrared-transmissive dome, such as for infrared imaging applications. For example, an infrared camera system includes a housing having a lens coupled to the housing and an infrared detector within the housing configured to receive infrared energy passing through the lens. An infrared-transmissive dome, coupled to the infrared camera system, includes a main body providing a hollow, hemispherical-shaped dome, with the main body made of an ultra-high molecular weight or a very-high molecular weight polyethylene material. The main body may have a wall thickness equal to or less than approximately 0.012 inches to allow infrared transmittance greater than approximately sixty five percent through the main body to the lens for infrared imaging in a wavelength range of approximately three to fourteen micrometers.
