38-278 9.0mm Dia. x 25mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm
This is a 38-278 Plano-Convex Lens, sourced from the reputable optical vendor, Edmund Optics. The lens boasts a 9.0mm diameter and a focal length of 25mm, making it suitable for a wide range of optical applications. The lens is made from the high-quality material, n-BK7 Schott, which is known for its excellent optical properties and durability.
The lens features a standard coating on both the front and back surfaces, specifically the EDM VIS-0 STD CURVE coating. This coating enhances the lens's performance within the visible light spectrum, particularly between 425-675nm. The coating helps to reduce surface reflections and increase transmission, thereby improving the overall efficiency and quality of the optical system.
The lens's geometry is another notable feature. It has a thickness of 1.19mm at the edge and 2mm at the center, providing a solid structure for precise optical alignment. The radius of curvature for the first surface is 12.92mm, and the back focal length is 23.68mm. The lens's shape is spherical, which is a common and versatile design in optical systems.
