The 32-012 is a 12mm diameter, double-convex lens with a focal length of 18mm, sourced from the renowned optical components vendor, Edmund Optics. This lens is uncoated and features a spherical design, making it suitable for a wide range of optical applications.
The lens's geometry is characterized by a thickness of 1.42mm at the edge and 3.48mm at the center, with an effective focal length (EFL) of 18mm. The first radius of curvature (R1) is 18.01mm, while the second radius (R2) is -18.01mm, indicating a convex-convex shape. The back focal length (BFL) is 16.81mm. The lens's inner and outer radii are both zero, suggesting a symmetrical design.
The lens is made of n-BK7 Schott, a popular optical glass known for its excellent optical properties. It is designed to work optimally at a wavelength of 587.6nm. The lens's coating is currently not specified, indicating it may be uncoated. However, this does not affect its performance in applications where coating is not a critical factor.
