ACN127-025-B 12.7 mm Dia. N-BAF10/N-SF6HT Unmounted Achromatic Doublet; EFL=-25mm 650-1050nm

The ACN127-025-B is a high-quality, unmounted achromatic doublet lens from Thorlabs, designed for use in the 650-1050nm spectral range. This lens is part of Thorlabs' extensive catalog of optical elements, which includes a wide variety of lenses, mirrors, beam splitters, and other components.

The lens features a 12.7 mm diameter and a thickness of 5.9 mm at the edge. It is composed of two elements, made from Schott's N-BAF10 and N-SF6HT materials, which are renowned for their optical quality. The lens's geometry includes a -13.6 mm radius of curvature on the first surface, a 17.1 mm radius on the second surface, and an 859 mm radius on the third surface. The center thicknesses are 1.5 mm and 2.8 mm for the first and second elements, respectively.

The ACN127-025-B is coated with Thorlabs' AC650-1050-B coating on both the front and back surfaces, which is designed to enhance its performance in the 650-1050nm spectral range. This lens is a multiplet, meaning it is composed of multiple elements, which allows it to achieve superior optical performance compared to a single element lens.

The lens is currently in stock and available for purchase through Thorlabs' website. With its high-quality materials, advanced coating, and superior optical design, the ACN127-025-B is an excellent choice for a wide range of optical applications.
