LA1050-AB 50.8 mm Dia. N-BK7 Plano-Convex Lens; EFL=100mm 400-1100nm
The LA1050-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 high-quality glass crown material known for its excellent optical properties, including low dispersion and high transmission across a wide range of wavelengths.
The lens features an effective focal length (EFL) of 100mm, making it suitable for a variety of applications that require moderate magnification and focusing capabilities. The front surface of the lens is coated with THo AB BAR, a broadband anti-reflection coating that enhances transmission and reduces surface reflections, particularly within the 400-1100nm spectral range.
The lens has a center thickness of 9.7 mm and an edge thickness of 3 mm, providing robustness and structural integrity. The curvature of the lens is defined by a radius of 51.5 mm on the convex side, while the plano side has an infinite radius. The lens is designed to operate in air, with an inner radius of 0 mm and an outer radius of 0 mm.
