LC2969-C 6 mm Dia. N-SF11 Plano-Concave Lens; EFL=-6mm 1050-1700nm
The LC2969-C is a Spherical Lens with a Plano-Concave base shape and a circular design, sourced from the reputable vendor Thorlabs. This lens has a diameter of 6 mm and a center thickness of 1.5 mm. The effective focal length (EFL) is -6 mm, making it a negative lens. The inner and outer radii are both 0 mm, indicating a symmetrical curvature.
This lens is made from N-SF11 Schott, a high-index glass material often used in infrared (IR) applications due to its excellent transmission properties in the 1050-1700 nm range. The lens is coated with THo C Bbar on both the front and back surfaces, which is a broadband anti-reflection coating designed to reduce surface reflections and improve transmission.
Please note that the lens's geometry and material properties are optimized for a central wavelength of 587.6 nm. This lens is in stock and ready for immediate dispatch, as indicated by its valid weblink status.
