The 45-957 is a Plano-Convex Spherical Lens, sourced from the renowned optical components vendor, Edmund Optics. This lens boasts a diameter of 2.5mm and a focal length of 2.0mm, making it a compact yet powerful optical component.
The lens is constructed from n-lasf9 Schott, a high-quality optical material known for its excellent transmittance and durability. The base shape of the lens is circular, contributing to its robust design and versatile application.
The geometry of the lens is meticulously crafted, with a thickness of 0.25mm at the edge and 0.8mm at the center. The lens's effective focal length (EFL) is 2mm, and its radius of curvature (R1) is 1.7mm. The back focal length (BFL) is 1.57mm, and both the inner and outer radii are 0mm, indicating a plano surface on the opposite side of the convex surface.
The lens features a coating of EDM NIR-I STD CURVE on both the front and back surfaces. This coating enhances the lens's performance in the near-infrared spectrum, specifically between 600 and 1050nm, making it suitable for a wide range of applications in this spectral range.
