AC254-100-AB 25.4 mm Dia. N-LAK22/N-SF10 Unmounted Achromatic Doublet; EFL=100mm 400-1100nm
The AC254-100-AB is a high-quality achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens is designed for use in a wide spectral range, from 400nm to 1100nm, making it a versatile choice for various optical applications.
The lens features a 25.4mm diameter and a thickness of 10.5mm at the edge. The geometry of the lens is complex, with three radii of curvature (r1: 92.4, r2: -48.2, r3: -152.8) and varying thickness at the center (8mm and 4mm). This design allows for superior optical performance, minimizing chromatic and spherical aberrations.
The lens is made from two types of high-quality Schott glass, N-LAK22 and N-SF10. These glasses are known for their excellent optical properties, including high transparency and low dispersion. The lens is coated with Thorlabs' proprietary anti-reflection coating, THo AB ACHROMATIC AR, on both the front and back surfaces. This coating reduces surface reflections, enhancing the overall transmission of the lens.
The lens is unmounted, providing users with the flexibility to integrate it into their custom optical systems. However, users should exercise caution while handling and mounting the lens to prevent damage.
