AC254-030-AB-ML 25.4 mm Dia. S-BAH11/S-TIH6 Mounted Achromatic Doublet; EFL=30mm 400-1100nm

The AC254-030-AB-ML is a mounted achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens, with a diameter of 25.4 mm, is designed for use within the spectral range of 400-1100nm, making it suitable for a wide range of optical applications.

The lens features a multilayer anti-reflection (AR) coating on both the front and back surfaces, denoted as 'tho ab achromatic ar'. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving overall system efficiency.

The lens geometry is intricate, with three radii of curvature (r1, r2, and r3) and varying thicknesses at the edge, center 1, and center 2. The edge thickness is 9.5mm, while the center thicknesses are 12mm and 3mm, respectively. The lens's design includes an inner radius of 0mm and an outer radius of 0mm, indicating a circular shape.

The lens is constructed from two types of materials, S-BAH11 and S-TIH6, both from Ohara. These materials are chosen for their specific refractive indices and dispersion properties, which contribute to the lens's achromatic performance.
