LB01-25-50 25.4 mm Dia. N-BK7 Double-Convex Lens; EFL=50mm Uncoated

This is a high-quality double-convex lens from CeNing Optics, designed for a wide range of optical applications. The lens has a diameter of 25.4 mm and an effective focal length (EFL) of 50mm, making it suitable for use in systems where a longer focal length is required.

The lens is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low coefficient of thermal expansion and high transmission in the visible spectrum. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, this also means that it is more cost-effective and suitable for applications where anti-reflection coatings are not necessary.

The lens has a spherical shape, with radii of curvature of 50.93 mm for the first surface and -50.93 mm for the second surface. This shape is often used in optical systems because it provides a wide field of view and low distortion. The lens has a thickness of 2 mm at the edge and 5.22 mm at the center, providing structural rigidity and resistance to deformation.
