AC254-050-C-ML 25.4 mm Dia. N-LAK22/N-SF6HT Mounted Achromatic Doublet; EFL=50mm 1050-1700nm
The AC254-050-C-ML is a multiplet lens with a diameter of 25.4 mm, specifically designed for use in the infrared spectrum, between 1050 and 1700 nm. This lens is a product of Thorlabs, a leading manufacturer of optical components.
The lens is composed of two distinct materials, N-LAK22 and N-SF6HT, both from Schott. These materials are chosen for their specific optical properties, which allow the lens to function effectively within its designated spectrum. The lens is coated with THo AC1050-1700-C on both the front and back surfaces, further enhancing its performance in the infrared range.
The lens has a base shape of a circle and features a multifaceted geometry. The edge thickness is 7.4 mm, while the center thicknesses are 9 mm and 1.8 mm. The lens's inner and outer radii are 0 mm, and it has three distinct radii (r1, r2, and r3) of 22.9 mm, -25.9 mm, and 194.5 mm, respectively.
This lens is mounted, making it ready for immediate use in optical systems. The catalog number for this lens is AC254-050-C-ML, and it is currently in stock on Thorlabs' website. The link to the product page is provided for your convenience.
