AC508-1000-B-ML 50.8 mm Dia. N-BAF10/N-SF10 Mounted Achromatic Doublet; EFL=1000mm 650-1050nm

The AC508-1000-B-ML is a mounted achromatic doublet lens, designed and manufactured by Thorlabs. This lens is specifically engineered for use within the 650-1050nm wavelength range, making it suitable for a variety of applications within this spectrum.

The lens features a 50.8 mm diameter, with a thickness of 6.4 mm at the edge. The inner and outer radii are 0, and the first and second radii of curvature are 494.3 mm and -398.1 mm, respectively. The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their optical quality and durability.

The lens is coated with Thorlabs' proprietary AC650-1050-B coating on both the front and back surfaces. This coating is designed to enhance the lens' performance within the 650-1050nm wavelength range, providing improved transmission and reduced reflection.

The lens is a multiplet, meaning it is composed of multiple elements. This design allows for the correction of chromatic aberrations, providing a sharper image across the entire wavelength range. The lens' shape is circular, with a thickness of 4.2 mm and 2.8 mm at the center, respectively.

The lens is currently in stock and available for immediate purchase. For more information, including detailed specifications and purchasing options, please refer to the product's webpage on Thorlabs' official website.
