ABSTRACT:
The invention relates to a protective cover which is complementary in shape to and is mounted on a sensing head such as that of a missile.
The protective device performs a dual function in that it is resistant to abrasion by impacting material such as dust, sand or ice, while at the same time being transparent to incident electromagnetic radiation which the sensing head is adapted to sense. The protective device may be moulded from a thin sheet (0.2 mm thick) of polytetra-fluoroethylene when this radiation is infrared.
