LP01-25-75 25.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=75mm Uncoated
This is a Plano-Convex lens, type of spherical lens with a circular base shape, manufactured by CeNing Optics. The lens has a diameter of 25.4 mm and a thickness at the edge of 2 mm. The center thickness is significantly larger at 4013 mm, providing a substantial base for the lens.
The Effective Focal Length (EFL) of this lens is 75 mm, making it a medium to long-range lens. The first radius of curvature (R1) is 38.9 mm, and the back focal length (BFL) is 72.27 mm. The lens does not have an inner or outer radius, indicating a uniform curvature.
The lens is made of N-BK7, a high-quality glass commonly used in optical systems due to its excellent optical properties. The wavelength for this lens is 546.1 nm.
Notably, this lens is uncoated. Coatings are often applied to lenses to reduce reflection and increase transmission, but this lens has been left uncoated, which may be suitable for certain applications.
The vendor, CeNing Optics, indicates that this lens is in stock and provides a link to their website for further information.
