LA1979 N-BK7 Plano-Convex Lens; Dia:2 in; f=200.0 mm Uncoated

The LA1979 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 2 inches, is designed for use in a wide range of optical systems, offering a focal length of 200.0 mm.

The lens is made of 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 an ideal choice for many optical applications. The Plano-Convex design of the lens, where one side is flat and the other is curved, allows for efficient light concentration and minimal spherical aberration.

The geometry of the LA1979 lens includes a thickness of 3 mm at the edge and 6.2 mm at the center. The effective focal length (EFL) is 200.0 mm, and the radius of curvature (R1) is 103 mm. The back focal length (BFL) is 195.3 mm, and the lens has no inner or outer radius, indicating a full circular shape.

This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While coatings can be beneficial in certain applications, an uncoated lens can be suitable when cost-effectiveness and simplicity are priorities.
