LA1472-A N-BK7 Plano-Convex Lens; Dia:9.0 mm; f=20.0 mm ARC 350-700nm
The LA1472-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 glass type known for its excellent optical properties, and has a diameter of 9.0 mm and a focal length of 20.0 mm.
The lens features an antireflection coating (ARC) designed for the 350-700nm wavelength range, which helps to reduce surface reflections and increase transmission. The front and back surfaces of the lens are coated with the same ARC, ensuring optimal performance from both sides.
The geometry of the lens includes a thickness of 1.5 mm at the edge and 2.5 mm at the center. The radius of curvature (R1) is 10.3 mm, and the back focal length (BFL) is 18.3 mm. The lens is spherical in shape, which is a common and versatile lens shape suitable for many applications.
The LA1472-A is available from Thorlabs and is currently in stock. For more information, including detailed specifications and purchasing options, please refer to the product webpage linked below.
