The 63-541 is a high-quality double-convex lens, sourced from the renowned optical components manufacturer, Edmund Optics. This lens is characterized by its 10mm diameter and a focal length of 50mm, making it suitable for a wide range of optical applications.
The lens is uncoated, which means it does not have any additional layers to enhance light transmission or reduce surface reflections. However, this does not compromise its performance in many applications, and it can be a cost-effective solution for users who do not require advanced coating features.
The lens geometry is spherical, with a base shape of a circle. The thickness at the edge is 2.01mm, while the center thickness is 2.5mm. The effective focal length (EFL) is 50mm, and the radii of curvature are 51.25mm for the first surface and -51.25mm for the second surface. The back focal length (BFL) is 49.17mm.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It is designed to work optimally at a wavelength of 587.6nm.
