67-537 20.0mm Dia. x 60.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-537 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 20.0mm and a focal length of 60.0mm, making it a versatile choice for various optical applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a plano-convex geometry, meaning one side is flat (plano) while the other side is curved (convex). The curvature of the convex side is defined by a radius of 18.09mm, and the lens has a central thickness of 4.5mm. The edge thickness is 1.48mm, providing robustness and durability.
The 67-537 lens is coated with Edmund Optics' NIR-II standard curve on both the front and back surfaces. This coating enhances its performance in the near-infrared spectrum, specifically between 750nm and 1550nm. The coating ensures high transmission and low reflection, making it ideal for applications that require optimal performance in the NIR range.
