AC064-015-B-ML 6.35 mm Dia. N-LAK22/N-SF6HT Mounted Achromatic Doublet; EFL=15mm 650-1050nm

The AC064-015-B-ML is a mounted achromatic doublet lens, designed and manufactured by Thorlabs. This lens is specifically engineered for use within the spectral range of 650-1050nm, making it suitable for a variety of applications within this range.

The lens features a base shape of a circle, with a diameter of 6.35mm. The edge thickness of the lens is 3.2mm, while the inner and outer radii are both 0mm. The lens's first radius of curvature (r1) is 10.3mm, its second radius of curvature (r2) is -7.8mm, and its third radius of curvature (r3) is -32.9mm. The center thickness of the lens at the first and second locations are 2.4mm and 1.5mm respectively.

The lens is composed of two materials, N-LAK22 and N-SF6HT, both from Schott. These materials have been carefully selected to provide the optimal performance within the specified spectral range. The lens is coated with Thorlabs' AC650-1050-B coating 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 the correction of optical aberrations, providing a clear, high-quality image. The lens is mounted, making it easy to integrate into existing systems or to use as a standalone component.

According to Thorlabs' website, the lens is currently in stock, making it readily available for immediate use. The lens's catalog number is AC064-015-B-ML, and it can be found on Thorlabs' website at https://www.thorlabs.com/thorproduct.cfm?partnumber=AC064-015-B-ML.
