LA1252-A N-BK7 Plano-Convex Lens; Dia:25.0 mm; f=25.4 mm ARC 350-700nm

The LA1252-A is a high-quality plano-convex lens from Thorlabs, designed for use in a wide range of optical applications. This lens is made from N-BK7, a popular optical glass known for its excellent optical properties, and is Schott-manufactured, ensuring a high level of precision and reliability.

The lens has a diameter of 25.0 mm and a focal length of 25.4 mm, making it a versatile choice for many setups. The edge thickness is 2.5 mm, while the center thickness is 11.7 mm, providing a good balance between weight and optical performance. The effective focal length (EFL) is also 25.4 mm, and the radius of curvature (R1) is 13.1 mm. The back focal length (BFL) is 17.7 mm, and both the inner and outer radii are 0 mm.

The LA1252-A is coated with a broadband anti-reflection coating (ARC) that covers the wavelength range of 350-700 nm. This coating reduces surface reflections, improving transmission and enhancing the overall performance of the lens. The shape of the lens is spherical, which is a common and versatile lens shape in optics.
