38-472 25.4mm Dia. x 35.0mm FL; VIS-EXT Coated; Plano-Convex Lens VIS-EXT 350-700nm

The 38-472 is a Plano-Convex Spherical Lens, sourced from the renowned optical components vendor, Edmund Optics. This lens boasts a diameter of 25.4mm and a focal length of 35.0mm, making it a versatile choice for various optical applications.

The lens is crafted from the high-quality material, n-BK7 Schott, a borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This material is particularly suitable for applications that require precision and durability.

The 38-472 lens features a VIS-EXT coating on both the front and back surfaces. This coating, specifically designed for the visible spectrum (350-700nm), enhances the lens's transmission capabilities, reducing unwanted reflections and improving overall light transmission. This feature makes the lens ideal for applications that require high light transmission and clarity, such as imaging systems, beam shaping, and collimation.

The lens's geometry is another notable feature. It has a thickness of 1.69mm at the edge and 6.9mm at the center, with an effective focal length (EFL) of 35mm. The radius of curvature for the first surface (R1) is 18.09mm, and the back focal length (BFL) is 30.46mm. These specifications contribute to the lens's high performance and versatility.
