The LA1540 N-BK7 Plano-Convex Lens is a high-quality optical component sourced from Thorlabs. This lens, with a diameter of 0.5 inches and a focal length of 15.0 mm, is designed for use in a wide range of optical systems.
The lens is made from N-BK7, a popular glass type in the optical industry due to its excellent optical properties. The Sub Type of this lens is Spherical, with a Plano-Convex base shape, meaning one side is flat while the other is curved. This design is often used to focus or collimate light in various applications.
The geometry of the lens includes a diameter of 12.7 mm, an edge thickness of 1.8 mm, and a center thickness of 5.1 mm. The effective focal length (EFL) is 15 mm, and the radius of curvature (R1) is 7.7 mm. The back focal length (BFL) is 11.6 mm, and both the inner and outer radii are 0 mm.
This lens is uncoated, meaning it does not have any anti-reflective coatings. While coatings can enhance the performance of a lens by reducing reflections and increasing transmission, uncoated lenses are often chosen for their cost-effectiveness and simplicity.
The vendor for this lens is Thorlabs, a leading global manufacturer of photonics equipment. The item's web link is valid and in stock, indicating that it is readily available for purchase and use in your optical system.
