LE1015-C 50.8 mm Dia. N-BK7 Positive Meniscus Lens; EFL=200mm 1050-1700nm
This LE1015-C lens is a 50.8 mm diameter Spherical Lens with a Positive Meniscus shape, sourced from Thorlabs. The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties. The lens features a convex-concave design, making it a converging lens that brings light rays to a focus.
The lens has an effective focal length (EFL) of 200mm, which is the distance from the lens's center to the point where the light rays converge. This makes the lens suitable for applications that require moderate magnification. The lens's geometry includes a thickness of 2.9mm at the edge and 6.2mm at the center, providing structural integrity and resistance to deformation.
The lens's front and back surfaces are coated with THo C Bbar, a broadband anti-reflection coating that reduces surface reflections and increases transmission across the 1050-1700nm wavelength range. This coating enhances the lens's performance in infrared applications.
