Description
The Fireye 46-58 is a precision quartz lens assembly engineered for use with Fireye 60-1290 flame scanner unions in industrial burner management systems. Installed directly in the 1/2″ union sight path, this lens enhances optical transmission while shielding the flame detection sensor from the damaging effects of heat, dirt, and combustion byproducts. Its quartz construction delivers exceptional high-temperature resistance alongside superior UV/IR transmission characteristics — ensuring accurate, stable flame signal detection in boilers, furnaces, and a wide range of combustion applications. The 46-58 helps maintain scanner sensitivity and system reliability in harsh industrial environments, extending the service life of flame monitoring equipment. It is an ideal replacement or upgrade component for Fireye UV flame detection setups where consistent optical clarity is critical to safe burner operation.
