LC2679-C 25.4 mm Dia. N-SF11 Plano-Concave Lens; EFL=-29.8mm 1050-1700nm

The LC2679-C is a 25.4 mm diameter Plano-Concave Spherical Lens, designed for use within the wavelength range of 1050-1700nm. This lens is sourced from Thorlabs, a reputable vendor known for their high-quality optical components.

The lens features a center thickness of 3.5mm and an effective focal length (EFL) of -29.8mm, making it suitable for a variety of optical applications. The plano-concave shape, characterized by a flat front surface and a curved back surface with a radius of curvature (R1) of -23.4mm, contributes to its unique optical properties.

The lens is crafted from N-SF11 Schott glass, a material known for its excellent optical properties and durability. The lens is coated with a broadband anti-reflection coating, denoted as 'tho c bbar' for both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections and increasing transmission efficiency.
