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 the thermal imaging lens, which provides a wider field of view to enhance situational awareness and enable more efficient and accurate analysis of thermal data.
With a Modulation Transfer Function (MTF) greater than 40% at 30-line pairs per millimeter (lp/mm), this lens offers high-resolution imaging capabilities, critical for detecting fine thermal details. Additionally, the lens achieves a relative illumination of 70%, ensuring that the brightness of the image remains consistent across the entire field of view, minimizing vignetting and enhancing image quality.
