This is a 48-785 Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens boasts a 30.0mm diameter and a focal length of 75.0mm, making it a versatile choice for various optical applications.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This material ensures high transmission in the visible spectrum and near-infrared range, making the lens suitable for use in applications such as beam shaping, collimation, and imaging.
The lens features a standard NIR I coating on both the front and back surfaces. This coating is specifically designed for the 600-1050nm wavelength range, enhancing the lens's performance in the near-infrared spectrum. The coating reduces reflection, increases transmission, and improves overall system efficiency.
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 zero, indicating a plano-convex shape. The radius of curvature of the convex surface is 38.76mm, and the back focal length is 70.95mm.
