LA7656-E2 25.4 mm Dia. ZnSe Plano-Convex Lens; EFL=50.1mm 4.5-7.5µm
The LA7656-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 50.1 mm and a thickness at the edge of 2.8 mm, which increases to 4 mm at the center.
The lens's geometry is characterized by a plano surface on one side and a convex surface with a radius of curvature (R1) of 70.2 mm on the other. The inner and outer radii are both zero, indicating a uniform curvature. The lens's design is spherical, which is a common choice for its ability to focus light to a single point, making it suitable for a wide range of optical applications.
According to the vendor's website, the LA7656-E2 is currently in stock, indicating its availability for immediate purchase and use. The website also provides a direct link to the product page for easy access to more detailed information or to place an order.
