AC508-180-AB-ML 50.8 mm Dia. N-LAK22/N-SF6 Mounted Achromatic Doublet; EFL=180mm 400-1100nm
The AC508-180-AB-ML is a multiplet lens, specifically an achromatic doublet, sourced from Thorlabs. This lens is designed for use within a broad spectral range, from 400 to 1100nm, making it a versatile choice for various optical applications.
The lens features a 50.8mm diameter, offering a substantial surface area for light transmission. The edge thickness of the lens is 10.2mm, providing structural integrity while minimizing unnecessary weight. The lens's geometry is intricately designed with three radii (r1, r2, and r3) and two central thicknesses, ensuring optimal light refraction and focusing.
The lens is composed of two materials, N-LAK22 and N-SF6, both from Schott. These materials are chosen for their specific refractive indices and dispersion properties, which contribute to the lens's achromatic performance. The lens is coated with THo AB Achromatic AR on both the front and back surfaces, further enhancing its optical performance by reducing surface reflections and increasing transmission.
This lens is mounted, making it ready for immediate use in optical systems. The mounting details are not specified in the provided data, so it's recommended to check the vendor's website or contact their customer service for more information.
