61-4914 Fireye LENS

Overview

The Fireye 61-4914 is a high-precision TC (Targeted Combustion) optical lens designed for use with Fireye flame scanner assemblies, particularly the InSight and Phoenix series. This specific model features a 9 degree skew angle, which allows the scanner to “look” slightly off-axis to better target a specific flame within a multi-burner environment. Constructed from high-quality glass, it is engineered to withstand the rigorous conditions of industrial combustion chambers while providing clear optical transmission for reliable flame detection.

Features

• 9-degree skew angle provides directional targeting to improve flame discrimination in multi-burner or complex furnace geometries.
• Durable glass construction ensures longevity and clarity in standard industrial operating temperatures.
• Part of a modular optical system, allowing for easy replacement or adjustment of the scanner’s field of view.
• Specifically designed to fit TC lens assemblies, ensuring precise alignment with the scanner’s internal sensors.
• Facilitates better signal-to-background ratios by focusing on the primary combustion zone of the targeted burner.

Specifications

• Part Number: 61-4914
• Lens Material: Glass
• Skew Angle: 9 degrees
• Lens Type: TC (Targeted Combustion)
• Compatibility: Used with Fireye InSight and Phoenix flame scanner optical housing assemblies (e.g., 60-1622)

Applications

The Fireye 61-4914 lens is primarily used in industrial power generation, petrochemical processing, and large-scale manufacturing plants. It is essential for applications requiring sophisticated flame discrimination, where multiple burners are located in close proximity and the scanner must distinguish its assigned flame from background radiation or adjacent burner flames. It is commonly installed in front of InSight series scanners to optimize the line-of-sight for both ultraviolet (UV) and infrared (IR) flame monitoring.
