67-564 25.4mm Dia. x 76.2mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 67-564 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens boasts a diameter of 25.4mm and a focal length of 76.2mm, 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 radius of curvature for the curved side is 19.69mm, and the lens has an effective focal length of 38.1mm. The lens's center thickness is 7mm, while the edge thickness is 2.36mm, providing a robust structure.
The lens is coated with EDM NIR-II std curve on both the front and back surfaces. This coating enhances its performance in the near-infrared spectrum, specifically between 750nm and 1550nm, making it ideal for applications such as night vision, thermal imaging, and spectral analysis.
