LA7660-E2 25.4 mm Dia. ZnSe Plano-Convex Lens; EFL=75mm 4.5-7.5µm
The LA7660-E2 is a 25.4 mm diameter Plano-Convex lens made of ZnSe material, sourced from Thorlabs. This lens is designed for use with a wavelength of 10600 nm and features a coating of tho e2znsearc4500750 on both the front and back surfaces. The lens has a focal length (EFL) of 75 mm and a thickness of 3.2 mm at the edge, increasing to 4 mm at the center.
The lens's geometry is spherical, with a radius of curvature (R1) of 105.2 mm for the convex side. The inner and outer radii are both 0 mm, indicating a uniform curvature across the lens surface. The lens is available from Thorlabs and is currently in stock, according to the vendor's website.
This lens is a Spherical Lens of the Plano-Convex type, featuring a Circular base shape. The lens is designed for use in a wide range of optical applications, thanks to its specific material, coating, and geometric properties. Its ZnSe material and specific coating make it suitable for use in the infrared spectrum, while its Plano-Convex design ensures a wide field of view and low distortion.
