IdealPhotonics' mid-infrared lens is an optical component specifically designed for the 3-5μm or 8-12μm mid-far-infrared band. Utilizing infrared materials such as germanium (Ge) and zinc selenide (ZnSe) and a special coating process, it ensures efficient thermal radiation transmission and resistance to environmental interference, making it widely applicable in thermal imaging, gas detection, and military night vision.Parameters including infrared transmittance (>90%@3-5μm or 8-12μm), material (e.g., Ge/ZnSe), thermal shock resistance (ΔT>100℃), aberration correction (MTF@10lp/mm>0.5), and coating durability (salt spray/damp heat testing) directly determine its thermal signal capture efficiency and reliability in extreme environments.
