LA1576-B N-BK7 Plano-Convex Lens; Dia:9.0 mm; f=12.0 mm ARC 650-1050nm

The LA1576-B is a high-quality plano-convex lens from Thorlabs, designed for use in a wide range of optical applications. This lens is fabricated from N-BK7, a popular glass type known for its excellent optical properties, and is specifically designed for use in the 650-1050nm wavelength range.

The lens has a diameter of 9.0 mm and a focal length of 12.0 mm, making it a compact yet powerful option for a variety of setups. The edge thickness is 1.5 mm, while the center thickness is 3.4 mm, providing a robust and durable design. The front and back surfaces of the lens are coated with a broadband anti-reflection coating (ARC), specifically designed for the 650-1050nm range, which helps to reduce surface reflections and increase transmission.

The lens features a spherical shape, with a radius of curvature (R1) of 6.2 mm and a back focal length (BFL) of 9.7 mm. The inner radius is 0 mm, and the outer radius is also 0 mm, indicating a uniform curvature. The lens is designed to be used in a plano-convex configuration, with the flat side facing the incoming light.
