67-547 25.0mm Dia. x 60.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 67-547 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens boasts a diameter of 25.0mm and a focal length of 60.0mm, making it suitable for a wide range of applications.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It has a refractive index of 1.5168 at 587.6nm, which contributes to its high-performance capabilities.
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 18.11mm, which is the radius of the curvature of the curved surface. This geometry results in a back focal length of 30.42mm, providing a longer focal length for improved image formation.
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 near-infrared spectrum, specifically between 750nm and 1550nm. It ensures high transmission and low reflection, making it ideal for applications such as night vision, thermal imaging, and spectral analysis.
