LA7733-E3 12.7 mm Dia. ZnSe Plano-Convex Lens; EFL=20mm 7-12µm
The LA7733-E3 is a 12.7 mm diameter Plano-Convex lens made of ZnSe material, designed for use in the 7-12 µm wavelength range. This lens, sourced from Thorlabs, is a Spherical Lens with a Base Shape of Circular and a Sub Type of Spherical Lens. The lens geometry includes a 2 mm thickness at the edge, increasing to 2.7 mm at the center, and an Effective Focal Length (EFL) of 20 mm.
The LA7733-E3 features an Anti-Reflection Coating (AR) on both the front and back surfaces, specifically the tho e3znsearc7000120 coating. This coating is designed to reduce surface reflections, thereby increasing transmission and minimizing back reflections.
The Inner and Outer Radii of the lens are 0, indicating a Plano-Convex design. The Radius of Curvature (R1) of the curved surface is 28.1 mm.
This lens is available for purchase directly from the vendor, Thorlabs, and is currently in stock. For more detailed information, including technical specifications and purchasing options, please refer to the vendor's website using the provided weblink.
