LE7246-F 12.7 mm Dia. ZnSe Positive Meniscus Lens; EFL=15mm 8-12µm
The LE7246-F is a spherical lens with a convex-concave design, sourced from Thorlabs. This lens boasts a 12.7 mm diameter and is constructed from ZnSe material, specifically identified as 'znse connolly'. The lens's geometry includes an edge thickness of 2 mm and a center thickness of 2.9 mm, with an effective focal length (EFL) of 15 mm. The radii of curvature are 7.5 mm for the first surface and 9 mm for the second surface, resulting in a back focal length (BFL) of 11.6 mm.
The lens is coated with AR coating, specifically 'tho znse-arced 8-12', on both the front and back surfaces to enhance its performance within the 8-12 µm wavelength range. This lens is currently in stock and available for immediate purchase, as indicated by its valid web link status.
