Lencsék
Lencsék is the Hungarian word for lenses; in optics, lenses are transparent optical elements that refract light to form images, focus beams, or correct vision. They are usually made from glass or plastic and shaped with precise curvatures to achieve a specified refractive effect. Key performance parameters include focal length, diameter, material, and surface quality.
Common types are converging (convex) lenses, which bring parallel light to a focal point, and diverging (concave)
Materials include crown and flint glass, as well as plastics such as polycarbonate and acrylic. Optical coatings,
Applications range from photography and cinematography to microscopy, astronomy, eyewear, and projection systems. In eyeglasses, lenses
Manufacture involves grinding, polishing, and edge finishing of individual elements, followed by precise assembly in housings
