The 38-348 is a Plano-Convex Spherical Lens, sourced from the renowned optical components vendor, Edmund Optics. This lens boasts a circular base shape with a 12.5mm diameter, making it suitable for a wide range of optical applications.
The lens features a 1.5mm thickness at the edge, increasing to 3.75mm at the center, providing a robust structure while maintaining a manageable profile. The effective focal length (EFL) is 12.5mm, ensuring a focused beam of light. The lens's front radius of curvature (R1) is 9.81mm, and the back focal length (BFL) is 10.4mm, contributing to its overall optical performance.
The lens is crafted from n-SF11 Schott, a high-index glass with excellent optical properties. This material is particularly suitable for near-infrared (NIR) applications, as it offers high transmission in the 600-1050nm range.
The lens is coated with EDM NIR-I Standard Curve on both the front and back surfaces. This coating enhances its performance in the NIR spectrum, reducing reflection and increasing transmission. The coating is designed to maintain high performance across a wide angle of incidence, making it ideal for diverse optical systems.
