The AC254-100-C-ML is a multiplet lens, specifically an achromatic doublet, sourced from Thorlabs. This lens is designed for use in the 1050-1700nm wavelength range, making it suitable for a variety of applications in the near-infrared spectrum.
The lens features a 25.4 mm diameter and a thickness of 6.6 mm at the edge. The geometry of the lens is complex, with three radii of curvature (r1, r2, r3) and two centers of thickness (thickness center 1, thickness center 2). The r1 radius is 32.1 mm, r2 is -38 mm, and r3 is 93.5 mm. The thickness at the center of the lens is 6.5 mm for the first center and 1.8 mm for the second center.
The lens is made from two types of Schott glass: N-BAF10 and N-SF6HT. These materials were chosen for their specific optical properties, which contribute to the lens's overall performance. The lens is coated with Thorlabs' AC1050-1700-C coating on both the front and back surfaces to enhance its optical properties within the specified wavelength range.
The lens is mounted, which means it is ready for immediate use in optical systems. The vendor for this item is Thorlabs, a well-known and respected manufacturer of optical components. The lens is currently in stock, according to the vendor's website, and the link provided leads directly to the product page for easy purchasing.
