48-235 30.0mm Dia. x 75.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm

This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as 48-235, boasts a diameter of 30.0mm and a focal length of 75.0mm, making it suitable for a wide range of optical applications.

The lens is made from the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This material is widely used in various optical systems due to its excellent transmittance in the visible spectrum.

The lens features a standard coating on both the front and back surfaces, specifically the EDM VIS-0 STD CURVE coating. This coating is designed to enhance the lens's performance in the visible light spectrum, between 425-675nm. It provides improved light transmission, reduced reflection, and increased durability, making it an ideal choice for applications that require high-quality optical performance.

The geometry of the lens includes a thickness of 3.08mm at the edge and 6.1mm at the center. The lens's inner and outer radii are both 0mm, indicating a flat surface on the non-curved side. The radius of curvature of the curved surface is 38.76mm, and the back focal length is 70.95mm.
