LA1779-AB 50.8 mm Dia. N-BK7 Plano-Convex Lens; EFL=1000mm 400-1100nm

The LA1779-AB is a Plano-Convex Spherical Lens with a diameter of 50.8 mm, sourced from the renowned optical components manufacturer, Thorlabs. This lens is made from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility. The lens has a center thickness of 3.6 mm and an edge thickness of 3 mm, providing a robust structure suitable for various applications.

The lens's effective focal length (EFL) is 1000 mm, making it ideal for use in systems requiring long focal lengths. The wavelength of operation is 587.6 nm, which falls within the visible light spectrum, although the lens is also suitable for use in the broader spectral range of 400-1100 nm.

The LA1779-AB lens features anti-reflection broadband coatings on both the front and back surfaces, denoted as 'tho ab bbar'. These coatings are designed to minimize surface reflections, thereby increasing transmission and improving overall system performance. The coating's broadband nature ensures low reflectance over a wide range of wavelengths, making this lens a versatile choice for many optical systems.
