AC508-1000-C-ML 50.8 mm Dia. SF5/N-SF6HT Mounted Achromatic Doublet; EFL=1000mm 1050-1700nm
The AC508-1000-C-ML is a mounted achromatic doublet lens, designed and manufactured by Thorlabs. This lens boasts a 50.8 mm diameter and an effective focal length (EFL) of 1000mm, making it suitable for a wide range of applications within the 1050-1700nm spectral range.
The lens is constructed from two types of Schott glass, SF5 and N-SF6HT, which are renowned for their optical properties. The SF5 glass is used for the first element, while the N-SF6HT glass is used for the second element. This combination helps to minimize chromatic aberration, a common issue in optical systems.
The lens features a multiplet geometry, with three radii of curvature (r1, r2, and r3) and three thicknesses (edge, center 1, and center 2). The edge thickness is 8.1mm, while the center thicknesses are 6mm and 3mm, respectively. The inner and outer radii are both zero, indicating a circular shape.
The lens is coated with Thorlabs' proprietary AC1050-1700-C coating on both the front and back surfaces. This coating is specifically designed to enhance the lens' performance within the 1050-1700nm spectral range.
The lens is mounted, making it easy to integrate into optical systems. The catalog number AC508-1000-C-ML is valid and in stock, according to Thorlabs' website. This indicates that the lens is readily available for purchase and delivery.
