The 84-329 is a high-quality achromatic doublet lens, boasting a 6.25 mm diameter and an effective focal length (EFL) of 20mm. This lens is designed for use in the ultraviolet-visible (UV-VIS) spectrum, specifically between 345-700nm, making it suitable for a wide range of applications.
The lens is composed of two elements, made from N-FK5 and F2HT Schott glass, respectively. These materials are chosen for their excellent optical properties, contributing to the lens's overall performance. The lens features a front coating of EDM UV-VIS std curve, and the back surface is also coated with the same standard curve, enhancing its transmission capabilities and durability.
The lens geometry is carefully designed, with an inner radius of 0mm and an outer radius of 0mm. The edge thickness is 2.8mm, while the center thickness is 2.4mm. The lens also features a first radius (r1) of 12.09mm, a second radius (r2) of -9.55mm, and a third radius (r3) of -25.35mm. These parameters contribute to the lens's excellent imaging capabilities.
