AC508-500-C 50.8 mm Dia. N-SF5/N-SF6 Unmounted Achromatic Doublet; EFL=499.7mm 1050-1700nm
The AC508-500-C is a 50.8 mm diameter achromatic doublet lens, designed and manufactured by Thorlabs. This unmounted lens is part of Thorlabs' extensive catalog of optical elements, and it is specifically designed for use in the 1050-1700nm spectral range.
The lens features a complex geometry, with a central thickness of 8.8mm and edge thickness of 9.9mm. The curvature of the lens is defined by three radii: r1=86.1mm, r2=-103.2mm, and r3=166mm. The lens is made from two types of Schott glass, N-SF5 and N-SF6, which are renowned for their optical quality and versatility.
The lens is coated with Thorlabs' AC1050-1700-C coating on both the front and back surfaces. This anti-reflection coating is specifically designed to minimize reflection losses in the 1050-1700nm range, thereby enhancing the lens's transmission and overall performance.
The AC508-500-C is currently in stock and available for immediate purchase through Thorlabs' website. The lens's detailed specifications and purchasing information can be found at https://www.thorlabs.com/thorproduct.cfm?partnumber=AC508-500-C.
