61-4913 Fireye LENS

Overview

The Fireye 61-4913, also designated as the TB lens, is a specialized optical component designed for use with fiber optic flame scanner assemblies. This glass lens is engineered with a specific 5-degree skew to optimize the field of view for flame detection in industrial combustion environments. It serves as a critical part of the optical interface, ensuring that the scanner can accurately monitor flame radiation even when the physical alignment of the scanner is not directly parallel to the burner’s flame path.

Features

• TB Lens designation for specific compatibility within the Fireye lens series
• 5-degree skew angle to provide a offset viewing path for better flame alignment
• High-quality glass construction suitable for standard industrial temperature ranges
• Part of a modular lens assembly system that allows for field replacement and customization
• Designed to work seamlessly with Fireye fiber optic bundles and inner carrier assemblies

Specifications

• Model Number: 61-4913
• Lens Type: TB (5-degree skew)
• Material: Glass
• Compatibility: Used with lens assemblies such as the 61-6864 (AB) or similar fiber optic mounting heads
• Weight: Approximately 2 lbs (shipping weight)
• Dimensions: 2 x 2 x 2 inches (standard packaging)

Applications

The 61-4913 glass lens is primarily used in industrial and commercial burner management systems that utilize Fireye InSight or Phoenix flame scanners with fiber optic extensions. It is ideal for installations where the burner geometry or windbox constraints prevent a straight line-of-sight to the flame, necessitating a skewed optical path. This lens is commonly applied in power generation plants, large industrial boilers, and complex furnace environments where precise flame discrimination is required.
