AC254-150-C 25.4 mm Dia. N-BAF10/N-SF6 Unmounted Achromatic Doublet; EFL=150.5mm 1050-1700nm

The AC254-150-C is a high-quality achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens, with a 25.4 mm diameter, is designed for use within the spectral range of 1050-1700nm, making it suitable for a wide range of applications in infrared spectroscopy, laser systems, and other optical technologies.

The lens features a multilayer anti-reflection coating, denoted as 'tho ac1050-1700-c', on both the front and back surfaces. This coating enhances transmission and reduces surface reflections, thereby improving overall system performance.

The lens geometry is complex, featuring three radii of curvature (r1, r2, r3) and two central thicknesses. The first surface has a radius of curvature of 42.7mm, the second surface has a radius of -52mm, and the third surface has a radius of 111.5mm. The edge thickness of the lens is 6.3mm, while the central thicknesses are 5mm and 2.5mm.

The lens is made from two types of Schott glass, N-BAF10 and N-SF6, each with specific refractive indices and dispersion properties that contribute to the lens's achromatic design. The use of these materials ensures high image quality and color correction over the specified spectral range.

The lens is unmounted, providing users with the flexibility to integrate it into their systems using their preferred mounting solution. The item data indicates that this lens is currently in stock, and the vendor's website link is provided for further information and purchasing.
