Optical engineering is a branch of engineering that focuses on the design and application of devices that manipulate light. This field involves creating instruments like lenses, mirrors, and fiber optics to improve vision and enhance imaging systems. Optical engineers work on technologies used in cameras, microscopes, and even lasers, making it essential for various industries, including healthcare and telecommunications. In addition to designing optical systems, optical engineers also study how light interacts with different materials. They explore concepts like refraction and reflection to develop innovative solutions for challenges in fields such as photography and astronomy. Their work helps advance technologies that rely on precise light manipulation.
