AC508-100-C 50.8 mm Dia. N-BAF10/N-SF6 Unmounted Achromatic Doublet; EFL=99.7mm 1050-1700nm

The AC508-100-C 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 spectral range of 1050-1700nm, making it suitable for a wide range of applications in infrared spectroscopy, laser systems, and other optical technologies.

The lens is a multiplet, meaning it is composed of multiple elements to achieve superior optical performance. The first element is made of N-BAF10 glass from Schott, while the second element is made of N-SF6 glass, also from Schott. This combination of materials helps to minimize chromatic aberration, a common issue in lens systems, ensuring high-quality imaging and accurate measurements.

The lens has a focal length of 99.7mm, as determined by its effective focal length (EFL). This, combined with its large diameter, makes it suitable for use in systems where high light-gathering power and excellent image quality are required.

The lens is coated with Thorlabs' proprietary AC1050-1700-C coating on both the front and back surfaces. This coating is designed to enhance the lens' performance in the 1050-1700nm range, improving transmission and reducing reflection.

The lens is unmounted, providing users with the flexibility to integrate it into their systems in the way that best suits their needs. It has a thickness of 12.8mm at the edge, with the center thicknesses of the two elements being 17mm and 2.5mm, respectively.

According to Thorlabs' website, the lens is currently in stock, making it readily available for immediate use in your optical systems. For more information, including detailed specifications and purchasing options, please refer to the provided weblink.
