Infrared optics is a branch of optics that deals with the manipulation and control of infrared light waves. Infrared light has longer wavelengths than visible light, and is commonly used in various technologies such as night vision devices, thermal imaging cameras, remote sensing, and communication systems. Infrared optics research focuses on designing and developing optical components and systems that can efficiently transmit, reflect, focus, and detect infrared light. This includes the development of lenses, mirrors, filters, and detectors that are specifically optimized for infrared wavelengths. Overall, the goal of infrared optics research is to improve the performance and functionality of infrared technologies, as well as to explore new applications in fields such as security, defense, astronomy, and medical imaging.
