61-6865 Fireye LENS

Overview

The Fireye 61-6865 is a precision-engineered quartz lens designed for use with Fireye industrial flame monitoring systems. Specifically identified as an AC lens with a 9-degree skew, this component is part of a specialized optical assembly used to enhance the sightline of flame scanners. The skew angle allows for refined alignment and target discrimination in complex burner configurations, ensuring the scanner accurately monitors the intended flame while minimizing interference from background radiation or adjacent burners.

Features

• Quartz Construction: Made from high-quality quartz to ensure durability and superior transmission of ultraviolet (UV) radiation in high-temperature environments.
• 9-Degree Skew: Features a specific 9-degree angular offset to assist in the precise orientation of the scanner’s field of view.
• Precision Optics: Designed to provide a clear, undistorted path for flame signals to reach the sensor.
• Thermal Resistance: Engineered to withstand the extreme ambient temperatures typically found near industrial burner sight pipes.

Specifications

• Model Number: 61-6865
• Lens Type: AC (Luminescent/Skewed)
• Skew Angle: 9 Degrees
• Material: Quartz (Fused Silica)
• Compatibility: Used with Fireye 60-1290 and 60-1622 long-range lens assemblies

Applications

The 61-6865 lens is primarily used in industrial and commercial combustion systems where standard straight-line viewing is insufficient. It is commonly applied in multi-burner furnaces, boilers, and kilns where precise flame discrimination is required to ensure safety and efficiency. It is compatible with Fireye InSight and 45UV5 series scanner assemblies that utilize fiber optic or long-range optical housings to monitor gaseous and liquid fuel flames.
