The 38-488-INK is a plano-convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 9.0mm diameter and a focal length of 25mm, making it suitable for a wide range of applications. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent transparency in the visible and near-infrared regions.
The lens features a visually transparent ink coating on both the front and back surfaces. This coating, referred to as 'edm visnir0sp2002000', is designed for the visible and near-infrared spectrum, specifically for wavelengths between 400 and 1000nm. This coating enhances the lens's performance in these regions, making it ideal for applications that require high-quality imaging or light transmission in the visible and near-infrared spectrum.
The lens's geometry is another notable feature. It has an edge thickness of 1.19mm and a center thickness of 2mm. The lens's inner and outer radii are both zero, indicating a plano-convex shape. The radius of curvature of the convex surface is 12.92mm, and the back focal length is 23.68mm.
