67-574 40.0mm Dia. x 40.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 67-574 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens boasts a diameter of 40.0mm and a focal length of 40.0mm, making it a versatile choice for various applications.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. It is coated with EDM NIR-II std curve on both the front and back surfaces, enhancing its performance in the near-infrared spectrum, specifically between 750-1550nm.
The geometry of the lens is characterized by a thickness of 3.08mm at the edge and 6.1mm at the center. The effective focal length (EFL) is 75mm, and the radius of curvature (R1) is 38.76mm. The back focal length (BFL) is 70.95mm, and the lens has no inner or outer radius, indicating a plano surface on the opposite side of the convex surface.
This lens is currently in stock, according to the vendor's website, and is ready for immediate use in your optical system. With its superior NIR performance and robust construction, the 67-574 Plano-Convex Lens is an excellent choice for a wide range of applications in the fields of imaging, spectroscopy, and more.
