LA2039-B 3 mm Dia. N-SF11 Plano-Convex Lens; EFL=9mm 650-1050nm
The LA2039-B is a 3 mm diameter Plano-Convex spherical lens made from N-SF11 Schott glass. This lens is designed for use in the 650-1050nm wavelength range, making it suitable for a wide range of optical applications. The lens has a focal length (EFL) of 9mm, which is the distance from the lens's center to the point at which light rays converge.
The lens features a plano-convex geometry, meaning one side is flat (plano) and the other is curved (convex). The radius of curvature (R1) of the curved surface is 7.1mm. The lens has a thickness of 1.2mm at the edge and 1.5mm at the center.
The LA2039-B is coated with Thorlabs' BBAR coating on both the front and back surfaces to reduce reflection and increase transmission. This coating is designed to work optimally at the specified wavelength range.
This lens is sourced from Thorlabs, a leading global manufacturer of photonics components. The item is currently in stock, according to the vendor's website. For more detailed information, please refer to the vendor's product page.
