67-480 9.0mm Dia. x 45.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 67-480 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens boasts a 9.0mm diameter and a focal length of 45.0mm, making it suitable for a wide range of applications. The lens is made from N-BK7 Schott, a popular optical glass known for its excellent transparency and low auto-fluorescence, making it ideal for use in the near-infrared (NIR) spectrum.
The lens features a plano-convex geometry, meaning one side is flat while the other is curved. The curvature of the lens is defined by a radius of 12.92mm, which contributes to its effective focal length (EFL) of 25mm. The lens has a central thickness of 2mm and an edge thickness of 1.19mm, providing a robust structure while maintaining a low profile.
The lens is coated with Edmund Optics' NIR-II standard curve coating on both the front and back surfaces. This coating enhances the lens's performance in the NIR spectrum, specifically between 750nm and 1550nm, by reducing surface reflections and increasing transmission. The coating also provides excellent environmental resistance, ensuring the lens maintains its performance even in challenging conditions.
