19mm F1.0 M22 12um AR Lens Long-wave Infrared Thermal Imaging Lens
19mm F1.0 M22 12um AR Lens Long-wave Infrared Thermal Imaging Lens is a 13mm F1.0 LWIR thermal lens working at 8–12μm, optimized for 640×512 (12μm pitch) uncooled infrared detectors. Core Strengths: 1.Ultra-large F1.0 aperture plus ≥90% high-transmittance AR coating delivers top-tier sensitivity for long-distance faint heat source detection; 2.Extra-high relative illumination ≥86% ensures uniform frame brightness and error-free temperature measurement at image edges; 3.Minimum focus distance of 0.5m supports close-up inspection of tiny components, while infinity focusing enables long-range patrol missions; 4.IP67 front lens protection and -40℃~+80℃ wide temperature range enable all-weather outdoor deployment without extra protective housings; 5.19mm focal length with narrow 22.85° horizontal FOV magnifies distant targets for clear long-distance defect identification. Main Applications: Long-distance power grid inspection, photovoltaic hot spot detection, precision industrial equipment predictive maintenance, long-range border & factory perimeter security, railway contact line monitoring, early forest fire warning. Important Note: Noticeable barrel distortion (<-10%) makes it perfect for temperature detection and target identification, but not recommended for high-precision dimensional measurement tasks.
