LA1433-D N-BK7 Plano-Convex Lens; Dia:1 in; f=150.0 mm ARC 1650-3000nm

The LA1433-D is a plano-convex lens made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. This lens, sourced from Thorlabs, boasts a diameter of 1 inch (25.4 mm) and a focal length of 150.0 mm. The lens's geometry includes a 2 mm thickness at the edge and a 3.1 mm thickness at the center, providing a solid structure for various applications.

The lens's effective focal length (EFL) is 149.5 mm, and its front radius (R1) is 77.3 mm. The back focal length (BFL) is 147.5 mm, and the lens has no inner or outer radius, indicating a uniform curvature. The lens's shape is spherical, a common choice for many optical applications due to its simple design and predictable optical behavior.

The LA1433-D is coated with a broadband anti-reflection coating (tho d bbar) on both the front and back surfaces, designed to operate within the wavelength range of 1650-3000 nm. This coating reduces surface reflections, enhancing the lens's transmission and overall performance in the specified wavelength range.
