The AC064-013-A-ML is a high-quality achromatic doublet lens from Thorlabs, designed for use in the 400-700nm spectral range. This lens is a multiplet, meaning it is composed of multiple optical elements to achieve superior performance. The lens features a 6.35mm diameter and a thickness of 3.1mm at the edge, making it compact and suitable for a wide range of applications.
The lens is made from two types of glass: n-BAK4 from Schott and SF5 from Schott. These materials are chosen for their excellent optical properties, including high transmittance and low dispersion. The lens is coated with THo AC400-700-A, a broadband anti-reflection coating that further enhances its performance by reducing surface reflections.
The lens has a focal length of 12.7mm, as determined by its effective focal length (EFL). This, combined with its achromatic design, makes it an excellent choice for applications that require high image quality over a wide spectral range. The lens's geometry is carefully designed to minimize optical aberrations, resulting in sharp, clear images.
