Optical cleaning refers to the process of removing dust, fingerprints, and other contaminants from optical surfaces, such as lenses and mirrors. This is crucial for maintaining the clarity and performance of optical devices like cameras, microscopes, and telescopes. Proper cleaning techniques help prevent scratches and damage to sensitive coatings. The cleaning process typically involves using specialized tools and solutions designed for optical surfaces. Common materials include microfiber cloths and lens cleaning solutions that are safe for coatings. Regular optical cleaning ensures that devices function optimally and provides clear images, enhancing the overall user experience.
