LC1259-A N-BK7 Plano-Concave Lens; Dia:25 mm; f=-50.0 mm ARC 350-700nm
The LC1259-A is a plano-concave lens with a diameter of 25 mm and a focal length of -50.0 mm, making it suitable for a wide range of optical applications. This lens is fabricated from N-BK7, a popular optical glass from Schott, known for its excellent optical properties and versatility.
The lens's geometry includes a thickness of 6.7 mm at the edge and 3.5 mm at the center, providing a balanced structure for efficient light transmission. The effective focal length (EFL) of -50.0 mm is a crucial parameter for designing optical systems, as it determines the convergence or divergence of light rays.
The LC1259-A features a broadband anti-reflection coating, ARC 350-700nm, which reduces surface reflections and increases transmission in the visible spectrum (350-700 nm). This coating is applied to both the front and back surfaces of the lens, ensuring optimal performance.
The lens's shape is spherical, a common geometry for optical elements due to its ease of manufacturing and excellent optical performance. The lens is sourced from Thorlabs, a leading vendor in the optical industry, ensuring high quality and reliability.
