87-919 5.0mm Dia. x 25.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm

The 87-919 is a Plano-Convex Spherical Lens, sourced from the renowned optical components vendor, Edmund Optics. This lens, with a 5.0mm diameter and a focal length of 25.0mm, is designed for use within the near-infrared spectrum, specifically between 600-1050nm.

The lens is fabricated from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The Plano-Convex geometry, where one side is flat and the other curved, is a common configuration for lenses used in various applications. The lens's central thickness is 1.6mm, while the edge thickness measures 1.36mm, providing a robust structure.

The lens features a standard EDM NIR-I coating on both the front and back surfaces. This coating is specifically designed to enhance performance within the near-infrared spectrum, ensuring optimal transmission and minimal reflection. The coating's standard curve ensures consistent performance and ease of integration into various optical systems.

The lens's inner and outer radii are both zero, indicating a simple, straightforward design. The first radius of curvature (R1) is 12.92mm, and the back focal length (BFL) is 23.95mm. These parameters, along with the lens's diameter and focal length, contribute to its overall optical performance.
