ACT508-1000-A-ML 50.8 mm Dia. N-BK7/N-SF2 Mounted Achromatic Doublet; EFL=1000mm 400-700nm
The ACT508-1000-A-ML is a high-quality achromatic doublet lens, designed and manufactured by Thorlabs. This lens is specifically designed for use in the 400-700nm spectral range, making it suitable for a wide range of applications in the visible spectrum.
The lens features a 50.8 mm diameter and has a focal length of 1000mm, as indicated by its EFL (Effective Focal Length) value. This combination of diameter and focal length results in a high level of optical precision and clarity. The lens is constructed from two types of glass, N-BK7 and N-SF2, both from Schott, which are renowned for their optical quality.
The lens is coated with Thorlabs' proprietary THo AC400-700-A coating on both the front and back surfaces. This coating is designed to optimize the lens' performance in the 400-700nm range, enhancing its transmission and reducing unwanted reflections.
The lens is mounted, providing a convenient and secure way to integrate it into optical systems. The mount includes threading for easy attachment to other optical components or mounting hardware.
