Abstract: A counter measure system is provided having a unitary infrared transparent dome including a look angle greater than 180. The dome has two hemispherical regions, with a second region having a truncated bottom end defining an opening to a central cavity inside which electro-optical elements are disposed. The electro-optical elements can view outward through the dome at the look angle. The second region on the dome has a complementary curvature as the first region by continuing a similar radius beyond a transverse horizontal axis or equator. The dome is mounted to a base, which also may be referred to as a bezel. The base defines a rabbet extending circumferentially about the base imaginary center defining an aperture. The base and the dome are formed from different materials but have equivalent coefficients of thermal expansion. In one embodiment the dome if formed from sapphire and the base is titanium.
