AC508-750-B-ML 50.8 mm Dia. N-BAF10/N-SF10 Mounted Achromatic Doublet; EFL=750mm 650-1050nm
The AC508-750-B-ML is a high-quality achromatic doublet lens from Thorlabs, designed with a 50.8 mm diameter and a focal length of 750mm. This lens is specifically engineered for use within the spectral range of 650-1050nm, making it an ideal choice for applications that require superior optical performance within this wavelength range.
The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their excellent optical properties. The use of these materials ensures high transmission and low dispersion, resulting in crisp, clear images with minimized chromatic aberration.
The lens features a multiplet design, with a center thickness of 4.2mm for the first element and 2.5mm for the second. This design, combined with the precision grinding of the lens surfaces, ensures excellent image quality and minimal distortion.
The AC508-750-B-ML is coated with Thorlabs' proprietary AC650-1050-B coating on both the front and back surfaces. This coating is specifically designed to enhance the lens' performance within the 650-1050nm spectral range, providing improved transmission and reduced reflection.
