AC127-025-B-ML 12.7 mm Dia. N-LAK22/N-SF6HT Mounted Achromatic Doublet; EFL=25mm 650-1050nm

The AC127-025-B-ML is a multiplet lens, specifically an achromatic doublet, sourced from Thorlabs. This lens is designed for use within the spectral range of 650-1050nm, making it suitable for a variety of applications within this range.

The lens features a 12.7 mm diameter and a thickness of 5.4 mm at the edge. The base shape is circular, and the lens is composed of two distinct materials: n-lak22 schott and n-sf6ht schott. These materials contribute to the lens's overall optical properties and performance.

The lens is coated with tho ac650-1050-b on both the front and back surfaces. This coating is designed to optimize the lens's performance within the specified spectral range.

The geometry of the lens is defined by several radii and thicknesses. The inner and outer radii are both 0, while the first radius (r1) is 16.2 mm, the second radius (r2) is -13.3 mm, and the third radius (r3) is -68.5 mm. The thickness at the center of the lens is 5 mm for the first center thickness and 2 mm for the second.

This lens is a mounted doublet, which means it is already assembled with a mount for easy integration into optical systems. The weblink provided leads to the product page on Thorlabs' website, where users can find more information and check the current stock status.
