Case Study: Wide Angle Thermal Imaging Lens

Introduction

Wide-angle thermal imaging lenses are advanced optical components designed to capture a broad field of view in thermal imaging applications. Unlike traditional narrow-angle lenses, these wide-angle lenses provide expansive coverage, making them ideal for applications that require comprehensive monitoring and detection. Thermal imagers equipped with wide-angle lenses can detect infrared radiation emitted by objects, translating it into visible images that highlight temperature differences. This technology plays a vital role in diverse fields, including surveillance, firefighting, search and rescue operations, industrial inspections, and environmental monitoring.  Avantier delves into this case study of thermal imaging lens, which provides a wider field of view to enhance situational awareness and enable more efficient and accurate analysis of thermal data.

Wide Angle Thermal Imaging Lens Specification

The table above shows an example of a wide-angle thermal imaging lens that features a focal length of 5mm and provides a field of view (FOV) of 90° by 70°, with a diagonal FOV of 120°. This expansive coverage allows for comprehensive surveillance and detailed thermal inspection in various environments. The lens maintains distortion levels below 30%, ensuring that the captured images are relatively free of significant optical aberrations that could distort the thermal data.
