LA7673-E3 12.7 mm Dia. ZnSe Plano-Convex Lens; EFL=40mm 7-12µm

The LA7673-E3 is a 12.7 mm diameter Plano-Convex lens made of ZnSe (Zinc Selenide) material, sourced from Thorlabs. This lens is designed for use with a wavelength of 10600 nm and features a focal length (EFL) of 40 mm, making it suitable for applications that require a longer focal length.

The lens has a front coating of tho e3znsearc7000120 and a back coating of the same, ensuring high transmission and durability. The edge thickness of the lens is 2 mm, while the center thickness is 2.4 mm, providing a good balance between weight and optical performance.

The lens's geometry is spherical, with a radius of curvature (R1) of 56.1 mm for the convex surface. The inner and outer radii are 0 mm, indicating a simple, straightforward design. The lens is circular in shape, allowing for versatile mounting and alignment options.
