Description
Plano-Concave Lenses are negative focus length lenses with a flat surface on one side and a spherical surface on the other. These lenses are designed to diverge incident light and are commonly used in optical systems to expand beams or increase focal lengths.
Available in various materials like BK7, UVFS, and CaF2, these lenses offer excellent surface quality, precision dimension tolerances, and optional anti-reflection coatings. Plano-Concave Lenses are versatile optical elements suitable for a wide range of applications in research, imaging, laser technology, and more.
