67-527-INK 18.0mm Dia. x 27.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-527-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 18.0mm and a focal length of 27.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750nm and 1550nm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens features a front and back coating of EDM NIR-II STD CURVE, a specialized coating designed for use in the NIR II spectrum.
The lens has a center thickness of 3.0mm and an edge thickness of 2.45mm. The inner radius is 0mm, and the outer radius is also 0mm, indicating a plano surface on both sides of the lens. The lens's effective focal length (EFL) is 100mm, and the back focal length (BFL) is 98.02mm.
The lens's geometry and material make it suitable for a wide range of applications in the NIR II spectrum, including biomedical imaging, optical communication, and spectral analysis. The EDM NIR-II STD CURVE coating ensures high transmission and low reflectance in the NIR II range, further enhancing its performance in these applications.
