39-522 12.7mm Dia. x 20mm FL; Uncoated; ZnSe Plano-Convex Lens
The 39-522 is a 12.7mm diameter, 20mm focal length plano-convex lens made of ZnSe material, sourced from Edmund Optics. This lens is uncoated, which means it does not have any additional layers to enhance its optical properties. The lens's geometry includes a 1.12mm thickness at the edge and 1.85mm at the center, with an effective focal length (EFL) of 20mm. The lens's inner and outer radii are both 0, and its shape is spherical.
The lens is designed to work with a wavelength of 10600nm, making it suitable for various applications in this spectrum range. Its base shape is circular, and it is a spherical lens, which means it has the same curvature throughout its surface. The lens's material ID is "znse marple-1964", which can be used for further reference or comparison with other materials.
Please note that the lens is uncoated, which means it may have higher reflectivity and lower transmission compared to coated lenses. However, uncoated lenses are often preferred for specific applications due to their lower cost and simpler manufacturing process. Always ensure that this lens meets your specific requirements before purchasing.
