AC254-080-B-ML 25.4 mm Dia. N-BAF10/N-SF6HT Mounted Achromatic Doublet; EFL=80.3mm 650-1050nm

The AC254-080-B-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 650-1050nm, making it suitable for a wide range of applications in the near-infrared region.

The lens features a focal length of 80.3mm, indicated by the 'EFL' parameter in its name. This focal length, combined with its diameter, allows the lens to provide a substantial light-gathering capability, making it ideal for use in high-resolution imaging systems and other applications where light collection is critical.

The lens is constructed from two types of glass, N-BAF10 and N-SF6HT, both from Schott. These materials are chosen for their excellent optical properties, including low dispersion and high transmission in the specified spectral range. The use of these materials helps to minimize chromatic aberration, a common issue in optical systems, thereby enhancing the overall image quality.

The lens is coated with Thorlabs' AC650-1050-B coating on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections, thereby improving transmission and enhancing the overall performance of the lens.

The lens is mounted, which adds to its convenience and ease of use. The mounting ensures the lens is securely held in place, reducing the risk of damage during handling and operation. It also facilitates easy integration into optical systems, making the lens a versatile choice for a wide range of applications.
