LA1254-AB 25.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=1500mm 400-1100nm
The LA1254-AB is a 25.4 mm diameter Plano-Convex lens made from N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion. This lens is designed for use in the 400-1100nm wavelength range, making it suitable for a wide range of optical applications.
The lens has an effective focal length (EFL) of 1500mm, which is the distance from the lens center to the focal point when the lens is imaging an object at infinity. This long focal length makes it ideal for high magnification applications.
The lens has a front coating of THo AB Bbar and a back coating of THo AB Bbar. These anti-reflection coatings are designed to reduce surface reflections and increase transmission, improving the overall efficiency of the lens.
The lens geometry includes a 2.1mm thickness at the edge and a 2mm thickness at the center. The front surface has a radius of curvature of 775.2mm, while the back surface is planar. The lens is spherical in shape.
This lens is available from Thorlabs, a leading global manufacturer of photonics equipment. According to the vendor, the lens is in stock, ensuring quick delivery for your optical project needs.
