LA1229-A N-BK7 Plano-Convex Lens; Dia:1 in; f=175.0 mm ARC 350-700nm
The LA1229-A is a high-quality plano-convex lens, designed and manufactured by Thorlabs, a leading global supplier of photonics equipment. This lens boasts a diameter of 1 inch (25.4 mm) and a focal length of 175 mm, making it suitable for a wide range of optical applications.
The lens is crafted from N-BK7, a popular optical glass due to its excellent optical properties and high Abbe number. This material ensures minimal chromatic aberration, making the LA1229-A ideal for applications that require high image quality and color correction.
The lens features a spherical shape, with a radius of curvature of 90.1 mm for the convex surface. The edge thickness is 2 mm, while the center thickness is 2.9 mm, providing robustness and durability. The effective focal length (EFL) of the lens is 175 mm, and the back focal length (BFL) is 172.5 mm.
The LA1229-A is coated with a broadband anti-reflection coating, designed to operate between 350 nm and 700 nm. This coating reduces surface reflections, enhancing the transmission of light through the lens and improving overall system performance.
