AC508-300-A-ML 50.8 mm Dia. N-BK7/SF2 Mounted Achromatic Doublet; EFL=300mm 400-700nm

The AC508-300-A-ML is a mounted achromatic doublet lens, designed and manufactured by Thorlabs. This lens is specifically engineered for use within the 400-700nm wavelength range, making it suitable for a wide array of optical applications. The lens features a 50.8 mm diameter and an effective focal length (EFL) of 300mm, providing a high level of optical precision and clarity.

The lens is constructed from two types of glass: N-BK7 from Schott and SF2 from Schott. These materials are carefully selected for their optical properties, contributing to the lens's overall performance. The lens also features a coating of THo AC400-700-A on both the front and back surfaces, further enhancing its optical capabilities.

The lens geometry is intricately designed, with an edge thickness of 5.4mm, an inner radius of 0mm, and an outer radius of 0mm. The lens also features three radii of curvature: r1 at 161.5mm, r2 at -134mm, and r3 at -580.8mm. The center thicknesses are 6mm for the first center and 2mm for the second center.

This lens is a multiplet, meaning it is composed of multiple elements. The multiplet design allows for the correction of optical aberrations, enhancing the lens's overall performance. The lens is mounted, providing a convenient and secure method of integration into optical systems.
