38-521 18.0mm Dia. x 20.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
This product is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens has a diameter of 18.0mm and a focal length of 20.0mm, making it suitable for a wide range of applications. The lens is made from n-sf11 Schott, a high-index glass with excellent optical properties.
The lens features a VIS-NIR coating, specifically the EDM VISNIR0SP2002000 coating, on both the front and back surfaces. This coating is designed to enhance the lens' performance in the visible and near-infrared spectrum, specifically between 400-1000nm. The coating reduces surface reflections, increasing transmission and improving overall image quality.
The geometry of the lens includes a thickness of 1.46mm at the edge and 4.3mm at the center. The radius of curvature (R1) is 15.7mm, and the back focal length (BFL) is 17.59mm. The lens is spherical in shape, a common and versatile geometry in optical systems.
According to the vendor's website, the lens is currently in stock, ensuring quick delivery times. This lens is a reliable and high-performing option for applications in the visible and near-infrared spectrum.
