LA1417-A N-BK7 Plano-Convex Lens; Dia:2 in; f=150.0 mm ARC 350-700nm
The LA1417-A is a plano-convex lens made of N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. This lens, sourced from Thorlabs, features a diameter of 2 inches (50.8 mm) and a focal length of 150.0 mm. The lens's design includes an antireflection coating (ARC) optimized for the wavelength range of 350-700 nm, which enhances its transmission capabilities.
The lens's geometry is characterized by its edge thickness of 3 mm and center thickness of 7.3 mm. The radius of curvature (ROC) for the curved surface is 77.3 mm, and the back focal length (BFL) is 144.7 mm. The lens's effective focal length (EFL) is 150.0 mm, which is the distance from the lens's principal point to the focal point. The lens's shape is spherical, and it has no inner or outer radius.
The lens's coating is a broadband antireflection coating (ARC), which is applied to both the front and back surfaces. This coating reduces surface reflections, thereby increasing the amount of light transmitted through the lens. The coating is specifically designed for the wavelength range of 350-700 nm, making it suitable for a wide range of optical applications.
