AC127-025-A 12.7 mm Dia. N-BAF10/N-SF10 Unmounted Achromatic Doublet; EFL=25mm 400-700nm

The AC127-025-A is a high-quality unmounted achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens is designed for use in the visible spectrum, specifically optimized for the 400-700nm range, making it suitable for a wide array of optical applications.

The lens features a base shape of a circle, with a diameter of 12.7 mm, ensuring a wide field of view. The geometry of the lens is intricately designed, with an inner radius of 0 mm, an outer radius of 0 mm, and three distinct radii (r1, r2, r3) that contribute to its unique optical properties. The edge thickness of the lens is 5.6 mm, while the center thicknesses are 5 mm and 2 mm, providing robustness and precision.

The lens is composed of two types of Schott glass, N-BAF10 and N-SF10, each with its specific refractive index and dispersion properties. This combination helps to correct chromatic aberrations, ensuring high-quality imaging. The lens is coated with Thorlabs' AC400-700-A coating on both the front and back surfaces, further enhancing its performance by reducing reflection and increasing transmission in the specified wavelength range.

The AC127-025-A is a multiplet lens, meaning it is composed of multiple elements. This design allows for more complex optical corrections and enhancements, making it a versatile choice for various applications. The lens is currently in stock and available for immediate purchase through the Thorlabs website, as indicated by its valid weblink status.
