LA2026-B 2 mm Dia. N-SF11 Plano-Convex Lens; EFL=6mm 650-1050nm
The LA2026-B is a 2 mm diameter Plano-Convex spherical lens, sourced from the reputable optical components manufacturer, Thorlabs. This lens is designed for use within the wavelength range of 650-1050nm, making it suitable for a wide range of optical applications.
The lens features an effective focal length (EFL) of 6mm, which is a crucial parameter in determining the lens's magnification and field of view. The EFL, combined with the lens's diameter, allows for a compact and efficient optical system. The lens's geometry includes a 0.8mm thickness at the edge and a 1mm thickness at the center, contributing to its robustness and ease of integration into optical setups.
The LA2026-B is made from N-SF11 Schott glass, a material known for its high refractive index and low dispersion. This makes the lens an excellent choice for applications that require high optical performance, such as imaging, beam shaping, and laser systems.
The lens is coated with THo BBAR, a broadband anti-reflection coating that reduces surface reflections and increases transmission across the entire wavelength range. This coating enhances the lens's performance in applications that require high transmission, such as interferometry and Fourier transform spectroscopy.
