LA1608 N-BK7 Plano-Convex Lens; Dia:1 in; f=75.0 mm Uncoated

The LA1608 N-BK7 Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of precision photonics. This lens, with a diameter of 1 inch and a focal length of 75.0 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. This material, also known as BK7, is a borosilicate crown glass with a low refractive index and low dispersion, making it an ideal choice for many optical applications. The lens's geometry features a plano-convex shape, meaning one side is flat while the other is curved, which is useful for focusing or collimating light beams.

The lens has a diameter of 25.4 mm, thickness at the edge of 2 mm, and thickness at the center of 4.1 mm. The effective focal length (EFL) is 75 mm, and the radius of curvature (R1) is 38.6 mm. The back focal length (BFL) is 72 mm, and the lens has no inner or outer radius, indicating it's a simple plano-convex lens.

Notably, this lens is uncoated. While coatings can be beneficial for reducing reflection, increasing transmission, or providing other specific optical properties, an uncoated lens can be suitable for many applications, especially where cost or simplicity is a consideration.

The LA1608 N-BK7 Plano-Convex Lens is currently in stock, according to the vendor's website, making it readily available for your optical system needs.
