ACT508-750-A-ML 50.8 mm Dia. N-BK7/N-SF2 Mounted Achromatic Doublet; EFL=750mm 400-700nm

The ACT508-750-A-ML is a mounted achromatic doublet lens, designed and manufactured by Thorlabs. This lens is part of Thorlabs' extensive catalog of optical elements, which 3DOptix integrates into its advanced optical simulation software. The lens is characterized by its 50.8 mm diameter and its effective focal length (EFL) of 750mm, specifically designed for use within the 400-700nm wavelength range.

The lens is constructed from two types of glass, N-BK7 and N-SF2, both from Schott. These materials are chosen for their optical properties, which contribute to the lens's overall performance. The lens's geometry is carefully designed, with an inner radius of 0mm, an outer radius of 0mm, and a center thickness of 6mm for both the first and second surfaces. The edge thickness of the lens is 11mm. The lens's surfaces are coated with Thorlabs' AC400-700-A coating, which is specifically designed for use within the 400-700nm wavelength range.

This lens is a multiplet, meaning it is composed of multiple optical elements. The specific design of this multiplet is not disclosed in the item data, but it is known to be achromatic. This means that the lens is designed to focus different wavelengths of light onto the same point, reducing chromatic aberration.

The lens is mounted, making it ready for immediate use in optical systems. The specifics of the mount are not disclosed in the item data, but it is known to be in stock and available for purchase.
