Optical design is the process of creating systems that manipulate light to achieve specific visual effects or functions. This field involves the use of lenses, mirrors, and other optical components to control how light travels and interacts with materials. Optical designers use principles of physics and mathematics to develop devices such as cameras, microscopes, and telescopes, ensuring they produce clear and accurate images. The goal of optical design is to optimize performance while minimizing aberrations, which are imperfections that can distort images. Tools like computer-aided design (CAD) software and ray tracing simulations are commonly used to model and analyze optical systems. This discipline is essential in various industries, including photography, medicine, and telecommunications.
