Lenses
In space and astronautical engineering, lenses are optical components that are used to focus or diverge light. They are used in various applications such as telescopes, cameras, and spectrometers. Lenses can be made from different materials such as glass, plastic, and crystals. They can also have different shapes and sizes depending on the application. The design of lenses is critical in space applications as they need to withstand extreme temperatures, radiation, and vacuum conditions. The performance of lenses can be affected by various factors such as aberrations, scattering, and diffraction. Therefore, the design and manufacturing of lenses require advanced techniques and technologies. In addition, lenses need to be tested and calibrated before they are used in space missions.
