LA1213-B N-BK7 Plano-Convex Lens; Dia:0.5 in; f=50.0 mm ARC 650-1050nm
The LA1213-B is a Plano-Convex lens, a type of spherical lens, sourced from Thorlabs, a renowned optical components manufacturer. This lens is designed with a circular base shape and features a diameter of 12.7 millimeters, making it suitable for a wide range of optical applications.
The lens has a thickness of 1.8 millimeters at the edge and 2.6 millimeters at the center, providing a robust structure. It boasts an effective focal length (EFL) of 50 millimeters, which is a crucial parameter in lens selection. The curvature of the lens is defined by a radius of 25.8 millimeters on the planar side and 48.1 millimeters on the convex side.
The LA1213-B is made from n-BK7, a high-quality optical glass from Schott, ensuring excellent optical performance. It is designed to work with a wavelength of 587.6 nanometers, a common wavelength in visible light spectrum applications.
The lens is coated with a broadband anti-reflection coating, specifically the tho b bbar coating, on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving the overall efficiency of the optical system.
