Infrared Athermal Lens Description:
Focal Length 75mm F1.2 Infrared Athermal Lens For 640x480-17um Detector.
8-12um Wavelength Long Wave Germanium IR Lens For Drone Monitor, Car Monitor, Infrared Sights, etc.
Germanium is commonly used in long wave infrared lenses. Its strong durability, non-reactive chemistry and Konu hardness make it a suitable choice for harsh environments. However, one disadvantage of germanium lenses is that they are prone to severe blurring due to temperature changes in some cases. If temperature fluctuations are expected, we recommend ZnSe LWIR lenses, which maintain a more stable focus even with large temperature changes.
Our long-wave infrared zoom lenses provide sharp, high-resolution images over the entire zoom range. They are particularly suitable for machine vision applications that require accurate images. We offer unique and smooth zoom lenses.
