AC508-300-B 50.8 mm Dia. N-LAK22/N-SF6HT Unmounted Achromatic Doublet; EFL=300mm 650-1050nm
The AC508-300-B is a high-quality unmounted achromatic doublet lens, designed and manufactured by Thorlabs. This lens is specifically engineered for use within the 650-1050nm wavelength range, making it suitable for a wide array of optical applications.
The lens features a base shape of a circle, with a diameter of 50.8mm. The edge thickness measures at 7.2mm, while the inner and outer radii are 0mm. The lens's first radius of curvature (r1) is 201.8mm, and the second radius (r2) is -161.5mm, with a third radius (r3) of -760mm. The center thickness of the first lens is 6.6mm, and the second is 2.6mm.
The lens is composed of two materials, N-LAK22 and N-SF6HT, both from Schott. These materials are known for their excellent optical properties, contributing to the lens's high performance. The lens is coated with THo AC650-1050-B on both the front and back surfaces, further enhancing its performance within the specified wavelength range.
The lens is a multiplet, meaning it is composed of multiple elements. This design allows for the correction of chromatic aberrations, ensuring high-quality imaging. The lens's effective focal length (EFL) is 300mm, making it suitable for use in various optical systems.
