The 48-719 is a Plano-Convex Spherical Lens, sourced from the renowned optical components vendor, Edmund Optics. This lens boasts a 6.0mm diameter and a focal length of 21.0mm, making it a compact yet powerful addition to any optical system.
The lens is crafted from N-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material ensures that the lens delivers sharp, high-contrast images across a wide spectrum of wavelengths, specifically within the 600-1050nm near-infrared range.
The 48-719 features a standard EDMM NIR-I coating on both its front and back surfaces. This coating enhances the lens's performance by reducing surface reflections and increasing 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 1.0mm at the edge and 1.42mm at the center, providing a robust structure without adding unnecessary weight. The lens's inner and outer radii are 0mm, indicating a uniform curvature that contributes to its high-quality imaging capabilities.
