The 38-298 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 12.5mm and a focal length of 100.0mm, making it suitable for a wide range 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 425-675nm. The coating reduces reflection and increases transmission, improving the overall efficiency and quality of the optical system.
The geometry of the lens includes a thickness of 1.22mm at the edge and 1.6mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a plano surface on one side. The lens's effective focal length (EFL) is 100mm, and the back focal length (BFL) is 98.95mm. The radius of curvature (R1) is 51.68mm.
