LA1384-C N-BK7 Plano-Convex Lens; Dia:2 in; f=125.0 mm ARC 1050-1700nm

The LA1384-C is a Plano-Convex lens, a type of spherical lens, sourced from the renowned optical components manufacturer, Thorlabs. This lens boasts a diameter of 2 inches, or 50.8 millimeters, and a focal length of 125.0 millimeters, making it suitable for a wide range of optical applications.

The lens is crafted from N-BK7, a high-quality borosilicate glass manufactured by Schott AG, which is known for its excellent optical properties and durability. The Plano-Convex geometry, where one side is flat and the other is curved, allows for efficient light collection and focusing.

The LA1384-C features an Anti-Reflection (AR) coating on both the front and back surfaces, specifically designed for the wavelength range of 1050-1700 nanometers. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving overall system efficiency.

The lens's geometry includes a thickness of 3 millimeters at the edge and 8.2 millimeters at the center, providing a solid structure for reliable optical performance. The back focal length (BFL) is 119.2 millimeters, and the effective focal length (EFL) is 125 millimeters, which are crucial specifications for lens selection and system design.
