LA1908-B N-BK7 Plano-Convex Lens; Dia:1 in; f=500.0 mm ARC 650-1050nm
The LA1908-B is a plano-convex lens from Thorlabs, designed with a spherical surface and a circular base shape. This lens is made from the high-quality material n-BK7 Schott, ensuring excellent optical performance. The lens has a diameter of 1 inch (25.4 mm) and a thickness of 2 mm at the edge, while the center thickness measures 2.3 mm. The effective focal length (EFL) of this lens is 500 mm, making it suitable for a wide range of applications.
The lens's front and back surfaces are coated with tho b bbar, a broadband anti-reflection coating designed for the 650-1050 nm wavelength range. This coating helps to reduce surface reflections, thereby increasing the amount of light transmitted through the lens. The inner and outer radii of the lens are 0, indicating a plano surface on one side and a curved surface on the other.
