This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as 45-482, is characterized by a diameter of 12.0mm and a focal length of 18.0mm, making it suitable for a wide range of applications.
The lens is constructed from n-SF5 Schott, a high-quality optical material known for its excellent transmission properties across the visible and near-infrared spectrum (400-1000nm). This makes the lens ideal for applications that require broadband transmission, such as imaging, spectroscopy, and beam shaping.
The lens features a plano-convex geometry, where one side is flat (plano) and the other side is curved (convex). This particular lens has a radius of curvature of 12.11mm on the curved side. The center thickness of the lens is 3mm, while the edge thickness is 1.41mm, providing a robust yet compact design.
The lens is coated with edm visnir0sp2002000, a broadband anti-reflection coating that is specifically designed for the visible and near-infrared range. This coating reduces surface reflections, enhancing the overall transmission of the lens and improving the quality of the optical system in which it is used.
