The 63-506 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 15.0mm and a focal length of 20.0mm, making it suitable for a variety of optical applications. The lens is made from n-sf5 Schott, a high-quality optical material known for its excellent transmittance and durability.
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 helps to reduce surface reflections, improving the overall transmission of light through the lens.
The geometry of the lens includes a thickness of 1.52mm at the edge and 3.8mm at the center. The inner and outer radii are both 0mm, indicating a flat surface on the uncoated side of the lens. The lens's effective focal length (EFL) is 20mm, and the back focal length (BFL) is 17.74mm.
