  • Industrial-grade infrared lens with high temperature-measurement accuracy and stable imaging
  • F0.8 ultra-large aperture delivers superior light sensitivity and image clarity

In industries where precision and reliability define performance, this infrared thermal imaging lens provides dependable results even under challenging conditions. Its F0.8 ultra-large aperture allows exceptional light intake, enabling accurate detection of faint thermal signals and precise temperature measurement.

Equipped with a 400×300@25μm sensor, the lens achieves a 22.64° × 17.03° field of view, ideal for mid-range monitoring. With 95% relative illumination and only 1% distortion, it ensures image consistency and accuracy. The 3.96 mm mechanical back focus and 12.5 mm image circle make integration seamless across multiple systems. Built for industrial temperature monitoring and gas detection, it delivers clarity, sensitivity, and reliability in every frame.
