67-509-INK 12.7mm Dia. x 19.1mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-509-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.7mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750nm and 1550nm.
The lens features a front and back coating of EDM NIR-II STD CURVE, which is standard for this type of lens. This coating enhances the lens's performance in the NIR II spectrum, making it ideal for applications that require precise optical performance in this range.
The lens has a thickness of 1.72mm at the edge and 4mm at the center. The effective focal length (EFL) is 12.7mm, and the back focal length (BFL) is 10.46mm. The inner radius is 0mm, and the outer radius is also 0mm, indicating a plano surface on the incident side.
This lens is made from N-SF11 Schott, a high-index glass that offers excellent transmission in the NIR region. The lens is inked, which is a common practice to mark lenses for identification and tracking purposes.
The lens's geometry and material make it suitable for a wide range of applications, including biomedical imaging, optical communication, and spectral analysis, among others. The lens is currently in stock, as indicated by its valid weblink status.
