The 32-871 is a 12mm diameter, double-convex lens with a focal length of 72mm, sourced from Edmund Optics. This lens is uncoated, which means it does not have any additional layers to protect the surface or enhance its optical properties.
The lens's base shape is circular, and it features a spherical geometry. The radius of curvature for the first surface (r1) is 73.97mm, while the second surface (r2) has a radius of curvature of -73.97mm. The lens's effective focal length (EFL) is 72mm, and the back focal length (BFL) is 71.07mm. The thickness at the edge of the lens is 2.31mm, and it increases to 2.8mm at the center.
The lens is made of n-BK7 Schott, a popular optical glass known for its excellent optical properties and high homogeneity. The lens is designed to operate at a wavelength of 587.6nm.
Please note that the lens is uncoated, which may affect its performance in certain applications. Uncoated lenses can be more susceptible to damage from environmental factors and may not perform as well in high-light conditions due to internal reflections. However, they are often more cost-effective and can be a good choice for applications where these factors are not a concern.
