AC508-100-A-ML 50.8 mm Dia. N-BAF10/N-SF10 Mounted Achromatic Doublet; EFL=100mm 400-700nm

The AC508-100-A-ML is a high-quality achromatic doublet lens from Thorlabs, designed with a 50.8 mm diameter and a focal length of 100mm. This lens is specifically designed for use in the 400-700nm spectral range, making it suitable for a wide range of applications in the visible spectrum.

The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their optical quality. The N-BAF10 glass is used for the first element, while the N-SF10 glass is used for the second element. This combination helps to correct chromatic aberrations, ensuring sharp and clear images.

The lens features a multiplet design, with a complex geometry that includes three radii of curvature (r1, r2, and r3) and three different thicknesses (thickness edge, thickness center 1, and thickness center 2). This design allows for precise control over the optical properties of the lens, enabling it to deliver high-quality performance.

The lens is coated with Thorlabs' AC400-700-A coating on both the front and back surfaces. This coating is designed to enhance the lens's transmission in the 400-700nm spectral range, further improving its performance in this region.

The AC508-100-A-ML is currently in stock and available for immediate purchase from Thorlabs. With its high-quality construction, precise design, and excellent performance, this lens is an excellent choice for a wide range of optical applications.
