AC127-025-AB-ML 12.7 mm Dia. N-LAK10/N-SF57 Mounted Achromatic Doublet; EFL=25mm 400-1100nm
The AC127-025-AB-ML is a multiplet lens, specifically an achromatic doublet, sourced from Thorlabs. This lens is designed for use within the spectral range of 400-1100nm, making it suitable for a wide range of optical applications.
The lens features a 12.7 mm diameter and a total thickness of 4.6 mm at the edge. The inner and outer radii are 0, indicating a circular shape. The first and second radii of curvature (r1 and r2) are 19.1 mm and -17.8 mm, respectively, while the third radius of curvature (r3) is -82.3 mm. The lens has two centers with different thicknesses: the first center thickness is 4 mm, and the second is 2 mm.
The lens is made from two types of Schott glass: N-LAK10 and N-SF57. Both the front and back surfaces of the lens are coated with Thorlabs' AB achromatic AR coating, which is designed to reduce surface reflections and improve transmission.
This lens is part of Thorlabs' extensive catalog and is currently in stock, according to the vendor's website. For more information, users can refer to the provided weblink.
