LA1252-C N-BK7 Plano-Convex Lens; Dia:25.0 mm; f=25.4 mm ARC 1050-1700nm

The LA1252-C is a high-quality Plano-Convex lens offered by Thorlabs, a leading global manufacturer of photonics components. This lens, designed from the renowned N-BK7 Schott glass, is specifically engineered for use within the wavelength range of 1050-1700nm, making it an ideal choice for near-infrared applications.

The lens boasts a diameter of 25.0 mm and a focal length of 25.4 mm, ensuring a generous effective focal length (EFL) for various optical arrangements. The front and back surfaces of the lens are coated with Thorlabs' proprietary broadband anti-reflection coating (ARC), which significantly reduces surface reflections and enhances overall transmission.

The lens's geometry is another notable feature, with a thickness of 2.5 mm at the edge and 11.7 mm at the center. The curvature of the lens is defined by a radius of 13.1 mm on the planar side and a back focal length of 17.7 mm. The lens's shape is spherical, ensuring excellent imaging quality and minimal optical aberrations.
