<P>PROBLEM TO BE SOLVED: To provide a flame detector that detects a flame with high sensitivity. <P>SOLUTION: The flame detector uses an infrared transmissive material made of either one of MgF<SB>2</SB>, spinel, CVD-ZnS, and transparent ZnS as a light transmissive window. At least one layer of antireflection coating layer is formed on one side or both sides of the infrared transmissive material. The antireflection coating layer is one or more layers formed of a metallic oxide layer and/or a metallic fluoride layer. <P>COPYRIGHT: (C)2010,JPO&INPIT |
