AC254-075-A 25.4 mm Dia. N-BK7/SF5 Unmounted Achromatic Doublet; EFL=74.9mm 400-700nm

The AC254-075-A 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 400-700nm, making it suitable for a wide range of applications within the visible light spectrum.

The lens features a geometry that includes an inner radius of 0mm, an outer radius of 0mm, and a base shape that is circular. The first radius of curvature (r1) is 46.5mm, the second radius (r2) is -33.9mm, and the third radius (r3) is -95.5mm. The edge thickness of the lens is 6.9mm, while the center thicknesses are 7mm and 2.5mm respectively.

The lens is composed of two types of glass: n-BK7 from Schott and SF5 from Schott. This combination of materials helps to correct chromatic aberrations, ensuring high-quality imaging. The lens is coated with tho ac400-700-a on both the front and back surfaces, further enhancing its performance within the specified spectral range.

The lens is a multiplet, meaning it is composed of multiple elements. This design allows for more precise control over the optical properties of the lens, making it suitable for more demanding applications.
