AC254-125-B 25.4 mm Dia. N-BK7/N-SF8 Unmounted Achromatic Doublet; EFL=125mm 650-1050nm

The AC254-125-B is a high-quality achromatic doublet lens, unmounted and with a diameter of 25.4 mm, sourced from the renowned optical component manufacturer, Thorlabs. This lens is designed for use within the spectral range of 650-1050nm, making it suitable for a wide array of applications within this range.

The lens features a geometry that includes an inner radius of 0mm, an outer radius of 0mm, and a thickness edge of 10mm. The first and second radii of curvature are r1=44.5mm and r2=-55.3mm, while the third radius of curvature is r3=930.5mm. The lens has a center thickness of 6mm for both the front and back.

The lens is composed of two types of materials: N-BK7 from Schott and N-SF8 from Schott. These materials are known for their excellent optical properties, contributing to the lens' high performance. The lens is coated with a broadband anti-reflection coating, specifically the tho ac650-1050-b coating, on both the front and back surfaces to minimize losses due to reflection.

This lens is classified as a multiplet, indicating that it is composed of multiple elements. The multiplet design helps to correct chromatic aberrations, making the lens an ideal choice for applications that require high-quality imaging or light transmission.
