AC254-050-A 25.4 mm Dia. N-BAF10/N-SF10 Unmounted Achromatic Doublet; EFL=50.2mm 400-700nm

The AC254-050-A is a 25.4 mm diameter achromatic doublet lens, unmounted and sourced from Thorlabs. This lens is designed for use within the 400-700nm spectral range, making it suitable for a wide range of optical applications. The lens features a focal length of 50.2mm, providing a compact and efficient optical solution.

The lens is composed of two elements, made from N-BAF10 and N-SF10 Schott glass. These materials have been carefully selected to minimize chromatic aberration, a common issue in optical systems. The lens is coated with Thorlabs' AC400-700-A coating on both the front and back surfaces, further enhancing its performance within the specified spectral range.

The lens geometry includes an edge thickness of 8.7mm, with the first and second radii of curvature measuring 33.3mm and -22.3mm respectively. The center thicknesses are 9mm and 2.5mm for the first and second elements respectively. The lens is designed in a circular shape, providing a wide field of view and symmetrical optical performance.

This lens is a multiplet, meaning it is composed of multiple elements. Multiplets are often used in optical systems to correct aberrations and improve image quality. The AC254-050-A is a versatile and high-performing lens, ideal for a variety of optical applications.
