LA1074-B N-BK7 Plano-Convex Lens; Dia:0.5 in; f=20.0 mm ARC 650-1050nm
The LA1074-B is a high-quality Plano-Convex lens, boasting a spherical geometry and a circular base shape. This lens is sourced from the renowned optical vendor, Thorlabs. The LA1074-B is designed with a diameter of 0.5 inches (12.7 mm) and a thickness at the edge of 1.8 mm, while the center thickness measures 4 mm. The effective focal length (EFL) of this lens is 20 mm, making it suitable for a wide range of optical applications.
The lens is crafted from n-BK7, a popular optical glass from Schott, which is known for its excellent optical properties. The curvature of the lens is defined by a radius of 10.3 mm on the planar side and 17.3 mm on the convex side. The back focal length (BFL) is 17.3 mm, and the inner and outer radii are 0 mm, indicating a plano surface on one side and a curved surface on the other.
The LA1074-B is coated with a broadband anti-reflection coating (ARC) that is designed to operate within the wavelength range of 650-1050 nm. This coating significantly reduces surface reflections, thereby enhancing the overall transmission of the lens. The coating is applied to both the front and back surfaces of the lens.
