üveglencsén

Üveglencsén is a Hungarian term that translates to "glass lens" or "lens of glass." It most commonly refers to the lens of a camera, telescope, or microscope, a piece of transparent material, typically glass or plastic, shaped to converge or diverge rays of light. The term is also used more broadly to describe any optical lens.

The shape of an üveglencsén is crucial to its function. It can be convex, meaning it bulges outwards, which converges light rays to a focal point, used in magnifying glasses and the objective lenses of telescopes. Alternatively, it can be concave, curving inwards, which diverges light rays, used in some types of eyeglasses to correct nearsightedness. Compound lenses, made of multiple üveglencsén elements, are often used in complex optical instruments to correct for aberrations and achieve higher image quality.

The material of an üveglencsén is also important. High-quality optical glass is commonly used due to its clarity, refractive properties, and durability. However, plastics are also employed, especially for less demanding applications or where weight reduction is a priority. The precise grinding and polishing of the üveglencsén surface are critical to its optical performance, determining how accurately it focuses light and the sharpness of the resulting image. In essence, an üveglencsén is a precisely engineered component fundamental to many scientific and imaging technologies.
