AC254-035-C 25.4 mm Dia. N-BAF10/N-SF6 Unmounted Achromatic Doublet; EFL=35.1mm 1050-1700nm
The AC254-035-C is a high-quality achromatic doublet lens, unmounted and with a diameter of 25.4 mm, sourced from the renowned optical components manufacturer, Thorlabs. This lens is designed for use within the wide spectral range of 1050-1700 nm, making it suitable for a variety of applications in infrared (IR) imaging and sensing systems.
The lens features a unique geometry, with an edge thickness of 8.8 mm and a center thickness of 11.5 mm at the first surface and 1.8 mm at the second surface. The lens curvature is defined by three radii: r1 = 23.2 mm, r2 = -17.9 mm, and r3 = -105.2 mm. The lens is made from two different materials, N-BAF10 and N-SF6, both from Schott, which contribute to its superior optical performance.
The AC254-035-C comes with anti-reflection (AR) coatings on both surfaces, specifically the Thorlabs' AC1050-1700-C coating, which is optimized for the 1050-1700 nm spectral range. This coating ensures high transmission and minimal reflection, further enhancing the lens's performance in IR applications.
