LA1560-C N-BK7 Plano-Convex Lens; Dia:0.5 in; f=25.0 mm ARC 1050-1700nm
The LA1560-C is a Plano-Convex lens, a type of spherical lens characterized by one flat and one curved surface. This lens, sourced from Thorlabs, features a circular base shape with a diameter of 12.7 mm and a thickness of 1.8 mm at the edge, increasing to 3.5 mm at the center. The effective focal length (EFL) of this lens is 25 mm, making it suitable for a variety of optical applications.
The lens is made from N-BK7, a popular glass type in the optical industry due to its excellent optical properties. The curvature of the lens is defined by a radius of 12.9 mm on the curved side, and the back focal length (BFL) is 22.6 mm. The lens does not have an inner or outer radius, indicating a uniform curvature.
The LA1560-C is coated with a broadband anti-reflection coating (ARC) designed for the wavelength range of 1050-1700 nm, which enhances its transmission capabilities within this spectrum. This coating is applied to both the front and back surfaces of the lens.
