67-494-INK 12.0mm Dia. x 15.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex lens, type of spherical lens, with a circular base shape and a diameter of 12.0mm. The lens is sourced from the renowned optical vendor, Edmund Optics. It is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750-1550nm.
The lens has a thickness of 1.84mm at the edge and 4.0mm at the center, providing a decent depth for light to pass through. The effective focal length (EFL) of the lens is 12mm, which is the distance from the lens's center to the focal point. The front and back surfaces of the lens are coated with the EDM NIR-II standard curve coating, enhancing its performance in the NIR II spectrum.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature across the lens. The back focal length (BFL) is 9.76mm, which is the distance from the lens's rear focal point to its surface.
This lens is made from N-SF11 Schott, a high-index glass with excellent transmittance in the NIR region. The lens is inked, which is a process where a dye is applied to the edge of the lens to indicate its orientation.
