67-176 30.0mm Dia. x 40.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 67-176 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 30.0mm diameter and a focal length of 40.0mm, making it suitable for a wide range of optical applications. The lens is made from n-sf11 Schott, a high-index glass with excellent optical properties.
The lens features a front and back coating of EDM NIR-I STD Curve, a specialized coating designed for use in the near-infrared spectrum, specifically between 600-1050nm. This coating enhances the lens's performance in the NIR range, providing improved transmission and reduced reflection.
The lens has a center thickness of 5mm and an edge thickness of 1.18mm, providing a robust and durable design. The inner and outer radii are 0mm, indicating a planar surface on one side and a curved surface on the other. The curvature of the lens is defined by a radius of 31.39mm on the curved side.
The lens's effective focal length (EFL) is 40mm, and the back focal length (BFL) is 37.2mm. These parameters are crucial in determining the lens's performance in a specific optical system.
