AC064-013-A 6.35 mm Dia. N-BAK4/SF5 Unmounted Achromatic Doublet; EFL=12.7mm 400-700nm

The AC064-013-A is a high-quality unmounted achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens is designed for use in the visible spectrum, specifically optimized for the 400-700nm range, making it suitable for a wide array of optical applications.

The lens features a base shape of a circle, with a diameter of 6.35mm. The edge thickness is 3.1mm, while the center thicknesses are 2.5mm and 1.5mm respectively. The lens is composed of two types of glass, n-BAK4 from Schott and SF5 from Schott, which are renowned for their excellent optical properties.

The lens is coated with THo AC400-700-A, a broadband anti-reflection coating, on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving overall system efficiency.

The lens is a multiplet, meaning it is composed of multiple elements. The curvature radii of these elements are r1=7.1mm, r2=-5.9mm, and r3=-40.4mm. The lens's effective focal length (EFL) is 12.7mm.
