LA1422-A N-BK7 Plano-Convex Lens; Dia:1 in; f=40.0 mm ARC 350-700nm
The LA1422-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, has a diameter of 1 inch (25.4 mm) and a focal length of 40.0 mm, making it suitable for a wide range of applications.
The lens's geometry includes a thickness of 2 mm at the edge and 6.4 mm at the center. The effective focal length (EFL) is 40 mm, and the radius of curvature (R1) is 20.6 mm. The back focal length (BFL) is 35.7 mm, and both the inner and outer radii are 0 mm.
The LA1422-A is coated with ARC 350-700nm on both the front and back surfaces. This anti-reflection coating reduces reflective losses, improving transmission in the visible spectrum (350-700 nm). The lens's shape is spherical, ensuring high-quality imaging and light transmission.
