AC050-008-A 5 mm Dia. N-BAF10/N-SF6HT Unmounted Achromatic Doublet; EFL=7.5mm 400-700nm

The AC050-008-A is a high-quality unmounted achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens is designed with a base shape of a circle, featuring a 5 mm diameter and a thickness of 3.7 mm at the edge. The lens is constructed from two types of Schott glass, N-BAF10 and N-SF6HT, which are renowned for their optical properties.

The lens geometry is intricately designed with three radii (r1, r2, and r3) and two center thicknesses. The first center thickness is 2.8 mm, while the second is 1.7 mm, contributing to the lens's overall optical performance. The lens's inner and outer radii are zero, indicating a simple, yet effective design.

The lens is coated with THo AC400-700-A on both the front and back surfaces, enhancing its transmission capabilities within the 400-700nm spectral range. This coating ensures high transmission and low reflection, making it ideal for a wide range of applications.

The lens is classified as a multiplet, indicating that it is composed of multiple elements. This design helps to correct chromatic aberrations, providing sharp and clear images. The effective focal length (EFL) of this lens is 7.5mm, making it suitable for use in compact optical systems.

According to the vendor's website, the lens is currently in stock, ensuring quick delivery upon order. The catalog number for this lens is AC050-008-A, and it can be found on Thorlabs' website at https://www.thorlabs.com/thorproduct.cfm?partnumber=AC050-008-A-ML.
