38-280 10.0mm Dia. x 17.5mm FL; VIS 0° Coated; Plano-Convex Lens VIS 0° 425-675nm
The 38-280 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 10.0mm diameter and a focal length of 17.5mm, making it suitable for a variety of optical applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a standard VIS 0° coating on both the front and back surfaces. This coating is designed to enhance the lens's performance in the visible light spectrum, specifically between 425 and 675nm. The coating helps to reduce surface reflections, improving the overall transmission of light through the lens.
The geometry of the lens includes a thickness of 1.29mm at the edge and 2.8mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a flat surface on the uncoated side of the lens. The lens's effective focal length (EFL) is 17.5mm, and the back focal length (BFL) is 15.66mm.
