LA1399 N-BK7 Plano-Convex Lens; Dia:2 in; f=175.0 mm Uncoated

The LA1399 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 to focus or collimate light in various optical systems.

The lens is made of N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is characterized by a high refractive index and low dispersion, making it an ideal choice for a wide range of applications. The lens's geometry features a plano-convex shape, meaning one side is flat while the other is curved. This design allows for efficient light collection and focusing.

The lens has a focal length of 175.0 mm, which is the distance between the lens and the point where it focuses light. This long focal length makes it suitable for applications that require a narrow beam of light or a large working distance. The lens's edge thickness is 3 mm, and its center thickness is 6.7 mm, providing structural rigidity and resistance to deformation.

The LA1399 is uncoated, meaning it does not have any anti-reflective or other coatings. While this may result in higher reflective losses, it also means the lens is more versatile and can be used in a wider range of wavelengths without the risk of coating damage.
