LA1074 N-BK7 Plano-Convex Lens; Dia:0.5 in; f=20.0 mm Uncoated

The LA1074 N-BK7 Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical equipment. This lens, with a diameter of 0.5 inches and a focal length of 20.0 mm, is designed for use in a wide range of optical systems, including imaging, beam shaping, and laser applications.

The lens is made from N-BK7, a popular glass type known for its excellent optical properties. The Plano-Convex design, where one side is flat and the other is curved, allows for efficient light collection and focusing. The geometry of the lens includes a diameter of 12.7 mm, an edge thickness of 1.8 mm, and a center thickness of 4 mm. The effective focal length (EFL) is 20 mm, and the radius of curvature (R1) is 10.3 mm. The back focal length (BFL) is 17.3 mm.

The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, uncoated lenses can still provide excellent performance in many applications, especially when the light source is not too powerful or does not contain significant amounts of aberration-inducing wavelengths.

The LA1074 N-BK7 Plano-Convex Lens is currently in stock, according to the vendor's website. For more detailed information, you can visit the product page at https://www.thorlabs.com/thorproduct.cfm?partnumber=LA1074.
