67-228 50mm Dia. x 75mm FL UV-VIS Coated; UV Plano-Convex Lens UV-VIS 250-700nm
The 67-228 is a UV-VIS coated Plano-Convex lens, sourced from the reputable optical vendor, Edmund Optics. This lens boasts a diameter of 50mm and a focal length of 75mm, making it suitable for a wide range of optical applications.
The lens is crafted from fused sil mal-1965, a material known for its excellent optical properties. The base shape of the lens is circular, and it features a spherical geometry. The edge thickness of the lens is 1.72mm, while the center thickness is 12.5mm. The lens has an EFL (Effective Focal Length) of 75mm and a BFL (Back Focal Length) of 66.43mm.
The 67-228 is coated with the EDM UV-VIS std curve on both the front and back surfaces. This coating enhances the lens's performance in the UV-VIS (Ultraviolet-Visible) spectrum, specifically between 250-700nm. The coating ensures optimal transmission and reduces reflection, thereby improving the overall efficiency and quality of the optical system.
