The AC508-200-B is a high-quality achromatic doublet lens, designed and manufactured by Thorlabs. This lens, with a diameter of 50.8 mm, is part of Thorlabs' extensive catalog of optical elements, which 3DOptix integrates into its advanced optical simulation software.
The lens is designed with a base shape of a circle, featuring a geometry that includes an edge thickness of 10.1 mm, and a central thickness of 8.2 mm for the first center and 5 mm for the second. The lens's inner and outer radii are 0, and it has a effective focal length (EFL) of 200mm, specifically designed for use within the wavelength range of 650-1050nm.
The lens is composed of two types of materials, namely N-LAK22 and N-SF6HT, both from Schott. These materials are known for their optical quality and durability, making this lens suitable for a wide range of optical applications.
The lens is coated with Thorlabs' proprietary coating, AC650-1050-B, on both the front and back surfaces. This coating enhances the lens's performance within the specified wavelength range, providing improved transmission and reduced reflection.
