Reflective optics is a field of research that involves the study and design of optical systems that use reflective surfaces to manipulate light. These systems typically include mirrors or other reflective elements that are used to focus, magnify, or redirect light in various ways. Reflective optics are commonly used in telescopes, microscopes, cameras, and other imaging systems, as well as in laser devices and various other optical instruments. Researchers in this field work to optimize the performance of reflective optical systems, improve their design and efficiency, and develop new technologies for applications in a wide range of scientific, industrial, and consumer applications.
