LA1229-AB 25.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=175mm 400-1100nm

This LA1229-AB optical lens, sourced from Thorlabs, is a 25.4 mm diameter Plano-Convex lens, designed with a spherical geometry. The lens is made from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility.

The lens has a center thickness of 2.9 mm and an edge thickness of 2 mm, providing a robust structure suitable for various applications. The effective focal length (EFL) of this lens is 174.4 mm, making it suitable for applications that require moderate magnification.

The lens is coated with THo AB BAR on both the front and back surfaces, enhancing its transmission capabilities within the 400-1100 nm wavelength range. This broadband anti-reflection coating reduces surface reflections, thereby increasing the amount of light transmitted through the lens.

The LA1229-AB is a versatile lens, suitable for a wide range of applications, including but not limited to, imaging systems, beam shaping, and laser applications. With its robust construction, broadband coating, and moderate EFL, this lens is an excellent choice for users seeking a high-performance, general-purpose optical element.
