46-185 Fireye LENS Assembly

Overview

The Fireye 46-185 Magnifying Lens Assembly is a precision optical component designed to enhance the signal response and sensitivity of Fireye ultraviolet flame scanners, specifically the UV7 series. By utilizing a high-grade quartz magnifying lens, this assembly focuses and amplifies UV radiation from the burner flame, making it essential for applications with weak flame signals due to burner geometry or long sight pipes. The assembly includes a thermal barrier to protect scanner electronics from high ambient temperatures.

Features

• High-grade quartz magnifying lens (46-186) for superior UV transmission and signal amplification.
• Integrated 1/2 inch F.N.P.T. insulated coupling provides a thermal break between the burner and scanner.
• Enhances optical flame visibility to support accurate scanner alignment.
• Durable industrial construction designed to withstand harsh combustion environments.
• Helps reduce nuisance shutdowns by maintaining a stable flame signal.
