AC080-020-C 8 mm Dia. N-LAK22/N-SF6 Unmounted Achromatic Doublet; EFL=20mm 1050-1700nm

The AC080-020-C is an unmounted achromatic doublet lens, boasting a diameter of 8 mm and effective focal length (EFL) of 20 mm, specifically designed for use within the wavelength range of 1050-1700 nm. This lens is sourced from the esteemed optical component manufacturer, Thorlabs.

The lens features a multiplet shape, comprised of two distinct materials: N-LAK22 and N-SF6, both from Schott. The geometry of the lens includes an edge thickness of 3.7 mm, inner and outer radii of 0 mm, and three distinct radii (r1, r2, and r3) that contribute to its unique optical properties. The central thicknesses of the lens are 3.3 mm and 1.3 mm, further enhancing its capabilities.

The AC080-020-C is equipped with anti-reflection coatings on both the front and back surfaces, specifically designed for the wavelength range of 1050-1700 nm. These coatings, identified as THo AC1050-1700-C, ensure minimal loss of light due to reflection, thereby maximizing the efficiency of the optical system in which this lens is incorporated.

This lens is currently in stock and available for immediate purchase through the Thorlabs website, as indicated by its valid weblink status. The catalog number AC080-020-C uniquely identifies this component, making it easily referenced and accessible for users.
