LA1608-AB 25.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=75mm 400-1100nm
The LA1608-AB is a 25.4 mm diameter Plano-Convex lens made from N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion. This lens, sourced from Thorlabs, is designed for use within a wavelength range of 400-1100nm, making it suitable for a wide range of optical applications.
The lens features an effective focal length (EFL) of 75mm, providing a good balance between field of view and focus. The plano-convex design, where one side is flat and the other is curved, allows for efficient light collection and focusing. The lens has a thickness of 2mm at the edge and 4.1mm at the center, contributing to its robustness and durability.
The LA1608-AB lens is coated with THo AB Bbar on both the front and back surfaces. This anti-reflection coating reduces surface reflections, thereby increasing transmission and improving overall system performance. The coating is designed to operate within the specified wavelength range, further enhancing the lens's performance.
