LA1119 N-BK7 Plano-Convex Lens; Dia:18.0 mm; f=50.0 mm Uncoated

The LA1119 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 18.0 mm, is designed for use in a wide range of optical systems, offering excellent performance and reliability.

The lens is fabricated from N-BK7, a popular glass type known for its excellent optical properties. This material, also known as Schott glass, is characterized by a high refractive index and low dispersion, making it ideal for a wide range of optical applications. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, its bare glass surface can still provide satisfactory performance in many applications.

The lens's geometry is spherical, with a plano-convex shape. This means one side of the lens is flat (plano), while the other side is curved (convex). The curvature of the convex side is defined by a radius of 25.8 mm, while the lens's effective focal length (EFL) is 50.0 mm. The lens's thickness at the edge is 1.8 mm, while its center thickness is 3.4 mm. These parameters, along with the lens's high-quality N-BK7 material, contribute to its excellent optical performance.

The lens is designed to work with a wavelength of 587.6 nm, which falls within the visible light spectrum. This makes it suitable for use in applications that involve visible light, such as imaging systems, beam shaping, and laser applications.
