Abstract
A radiation pyrometer for a gas-turbine engine has a sapphire lens that focusses radiation from the turbine blades onto the end of a fibre-optic cable. The front, exposed surface of the lens has a vapor deposited layer comprising a mixture of platinum and aluminum oxide which acts as a catalyst to promote oxidation of soot to a gaseous form and thereby reduce contamination of the lens.
