AC254-200-AB-ML 25.4 mm Dia. N-LAK22/N-SF10 Mounted Achromatic Doublet; EFL=200mm 400-1100nm

The AC254-200-AB-ML is a high-quality mounted achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens is designed with a 25.4 mm diameter and features an effective focal length (EFL) of 200mm, making it suitable for a wide range of optical applications within the 400-1100nm wavelength range.

The lens is constructed from two types of Schott glass, N-LAK22 and N-SF10, which are renowned for their excellent optical properties. The front and back surfaces of the lens are coated with Thorlabs' AB Achromatic AR coating, which is specifically designed to reduce chromatic aberration and improve overall image quality.

The lens geometry is carefully crafted, with an edge thickness of 7.3mm and inner and outer radii of 0mm. The lens features two curved surfaces, with radii of curvature of 117.1mm and -142.1mm, respectively. The center thicknesses of the lens are 5mm and 3mm, ensuring minimal distortion and high-fidelity image transmission.

The lens is mounted, making it easy to integrate into existing optical systems. The vendor, Thorlabs, provides a comprehensive catalog of optical components, and the weblink to the product page is valid and indicates that the product is in stock, ensuring quick and reliable delivery.
