ACN127-020-A 12.7 mm Dia. N-BAF10/N-SF6HT Unmounted Achromatic Doublet; EFL=-20mm 400-700nm

The ACN127-020-A is a high-quality unmounted achromatic doublet lens, meticulously crafted by Thorlabs. This lens is designed for use in the 400-700nm spectral range, making it suitable for a wide array of optical applications.

The lens features a 12.7 mm diameter and a center thickness of 1.5mm for the first element and 3mm for the second. The lens's geometry is intricately designed with a range of radii (r1=-13.5mm, r2=14.3mm, r3=87.9mm) and edge thickness of 6.3mm, ensuring optimal performance.

The lens is composed of two Schott glasses, N-BAF10 and N-SF6HT, each with its unique refractive indices and dispersions, contributing to the lens's achromatic properties. The lens is coated with Thorlabs' AC400-700-A coating on both the front and back surfaces, enhancing its transmission capabilities within the specified spectral range.

This lens is classified as a multiplet, a complex lens system made up of multiple elements. The multiplet design of the ACN127-020-A allows for superior performance in terms of chromatic aberration correction and overall image quality.
