67-570 30.0mm Dia. x 60.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 67-570 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens boasts a 30.0mm diameter and a 60.0mm focal length, making it suitable for a wide range of applications. The lens is coated with EDM NIR-II Standard Curve on both the front and back surfaces, enhancing its performance in the near-infrared spectrum, specifically between 750nm and 1550nm.
The lens is made of n-SF11 Schott, a high-index glass with excellent transmittance in the NIR region. The plano-convex geometry, where one side is flat and the other is curved, provides a large, flat surface for easy integration into optical systems. The lens has a center thickness of 6.9mm and an edge thickness of 1.5mm, offering a balance between compactness and robustness.
The lens's effective focal length (EFL) is 30mm, and its back focal length (BFL) is 26.13mm. The radius of curvature (R1) is 23.54mm. The lens is spherical, ensuring high-quality imaging and minimal aberrations. The inner and outer radii are both zero, indicating a uniform curvature across the lens.
