67-513-INK 12.7mm Dia. x 44.5mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-513-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a circular base shape with a diameter of 12.7mm and a thickness of 1.31mm at the edge, transitioning to 1.7mm at the center. The effective focal length (EFL) of this lens is 100mm, making it suitable for a variety of applications.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties, including a high refractive index and low dispersion. This material is well-suited for use in the infrared spectrum, specifically the Near-Infrared II (NIR II) range of 750-1550nm, as indicated by the lens's coating.
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. This coating enhances the lens's performance in this specific range, making it an ideal choice for applications that require superior optical performance in the NIR II spectrum.
