1. An infrared camera system, comprising:

  • a housing;

    a lens coupled to the housing;

    an infrared-transmissive dome coupled to the infrared camera system; and

    an infrared detector within the housing and configured to receive infrared energy passing through the lens and the infrared-transmissive dome to capture infrared images, wherein;

    the infrared-transmissive dome comprises a main body providing a hollow, hemispherical-shaped dome;

    the main body is self-supporting and is made of an ultra-high molecular weight or a very-high molecular weight polyethylene material; and

    the main body has a wall thickness equal to or less than 0.012 inches and is configured 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.
