LA1422-C N-BK7 Plano-Convex Lens; Dia:1 in; f=40.0 mm ARC 1050-1700nm
The LA1422-C 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 front surface has a radius of curvature (R1) of 20.6 mm, while the back focal length (BFL) is 35.7 mm. The lens's effective focal length (EFL) is 40 mm, which is the distance from the lens's center to the focal point.
The LA1422-C is coated with a broadband anti-reflection coating (tho c bbar) on both the front and back surfaces, designed to operate within the 1050-1700 nm wavelength range. This coating reduces surface reflections, thereby increasing transmission and minimizing ghost images and flare.
The lens's shape is spherical, a common choice for its ease of manufacturing and good imaging performance. The base shape is circular, ensuring symmetry and consistency in the lens's performance.
