AC508-080-AB 50.8 mm Dia. N-LAK22/N-SF6 Unmounted Achromatic Doublet; EFL=80mm 400-1100nm

The AC508-080-AB is a high-quality achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens, with a diameter of 50.8 mm, is designed for use in the ultraviolet, visible, and near-infrared regions of the spectrum, specifically catering to the wavelength range of 400-1100nm.

The lens is composed of two distinct materials, N-LAK22 and N-SF6, both from the reputable Schott glass catalog. These materials are carefully selected to minimize chromatic aberration, a common issue in optical systems where different wavelengths of light are focused at different points. The achromatic design ensures that the lens focuses both red and blue light to the same point, providing sharp and clear images.

The lens features a focal length of 80mm, indicated by the EFL (Effective Focal Length) parameter. This makes it suitable for a wide range of applications, including imaging systems, beam shaping, and laser applications. The lens has a geometric profile with a central thickness of 12mm and edge thickness of 7.8mm, providing structural integrity and resistance to deformation.

The lens surfaces are coated with Thorlabs' AB ACHROMATIC AR coating, which is designed to reduce reflection and increase transmission across the entire spectral range. This coating enhances the lens' performance, particularly in systems where multiple reflections can lead to signal loss or unwanted artifacts.
