LA1304-C N-BK7 Plano-Convex Lens; Dia:0.5 in; f=40.0 mm ARC 1050-1700nm
The LA1304-C is a Plano-Convex lens, a type of spherical lens characterized by having one flat surface and one curved surface. This lens, sourced from Thorlabs, features a circular base shape with a diameter of 0.5 inches (12.7 mm) and a thickness of 1.8 mm at the edge, increasing to 2.8 mm at the center. The effective focal length (EFL) of this lens is 40 mm, making it suitable for a variety of optical applications.
The lens is made of N-BK7, a type of glass commonly used in optical systems due to its excellent optical properties. The curvature of the lens is defined by a radius of 20.6 mm on the curved side, and the back focal length (BFL) is 38 mm. The lens does not have any inner or outer radius, indicating a uniform curvature.
The LA1304-C is coated with a broadband anti-reflection coating (ARC) designed for use in the 1050-1700 nm wavelength range. This coating reduces unwanted reflections, improving the efficiency and performance of the lens. The coating is applied to both the front and back surfaces of the lens.
