45-296 25mm Dia. x 40mm FL Uncoated; Double-Convex Lens
The 45-296 25mm Dia. x 40mm FL Uncoated; Double-Convex Lens is a high-quality optical component sourced from Edmund Optics. This lens, with a diameter of 25mm, is designed for use in a variety of optical systems, offering a focal length of 40mm and a double-convex geometry.
The lens's base shape is circular, and it is made from the material n-bk7 schott, a popular choice in the optical industry due to its excellent optical properties. The lens's design includes an inner radius of 0 and an outer radius of 0, contributing to its spherical shape.
The lens's geometry is notable for its thickness at the edge, which measures 1.34mm, and its center thickness, which measures 5.3mm. The effective focal length (EFL) is 40mm, and the back focal length (BFL) is 38.21mm. The radii of curvature for the first and second surfaces are 40.42mm and -40.42mm, respectively.
This lens is uncoated, meaning it does not have any anti-reflective coatings. While coatings can enhance the performance of a lens by reducing reflections and increasing transmission, an uncoated lens can be suitable for certain applications where such enhancements are not necessary.
The lens is currently in stock and available for purchase through the provided weblink. With its robust design and high-quality materials, the 45-296 25mm Dia. x 40mm FL Uncoated; Double-Convex Lens is an excellent choice for a wide range of optical applications.
