Athermalized IR (Infrared) Lens is a specially designed infrared optical lens that compensates for temperature changes, maintaining focus without needing manual adjustment across a wide range of temperatures. These lenses are used in systems where temperature stability is crucial, such as thermal imaging cameras, infrared sensors, and other devices operating in variable environmental conditions.
Athermalized IR Lens 25mm F/1.0 is widely used in laser, medicine, astronomy, infrared night vision and other fields.
Our Athermalized IR Lens 25mm F/1.0 is carefully handled during storage and transportation to preserve the quality of our product in its original condition.
