67-571-INK 30.0mm Dia. x 75.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex lens, type of spherical lens, sourced from Edmund Optics, a renowned vendor in the optical industry. The lens has a circular base shape with a diameter of 30.0mm and a thickness of 1.18mm at the edge, increasing to 5.0mm at the center. The effective focal length (EFL) of the lens is 40.0mm, and the radius of curvature (R1) is 31.39mm. The back focal length (BFL) is 37.2mm, and the lens does not have any inner or outer radius.
The lens is made of n-SF11 Schott, a high-index glass with excellent transmittance in the near-infrared (NIR) region. The lens is coated with EDM NIR-II std curve on both the front and back surfaces, enhancing its performance in the NIR II region, specifically between 750-1550nm. This coating ensures high transmission and low reflection, making it suitable for various applications in the NIR spectrum.
The lens is inked, which is a common practice in the industry to mark lenses with their unique identification for traceability and quality control purposes. The inked mark does not affect the optical performance of the lens.
