45-131 3mm Dia. x 9mm FL Uncoated; Double-Convex Lens
The 45-131 3mm Dia. x 9mm FL Uncoated; Double-Convex Lens is a high-quality optical component sourced from Edmund Optics. This lens, with a diameter of 3mm, is designed for use in a variety of optical systems, offering a focal length of 9mm.
The lens is spherical in shape, specifically a convex-convex design, which means it has two curved surfaces that both bulge outwards. This design is often used to increase the optical power of a lens or to reduce its thickness and weight. The base shape of the lens is circular, contributing to its compact design and versatile application.
The geometry of the lens includes a thickness edge of 1.35mm and a thickness center of 1.6mm. The effective focal length (EFL) is 9mm, and the radii of curvature for the first and second surfaces are 9.02mm and -9.02mm, respectively. The back focal length (BFL) is 8.46mm.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This makes it an ideal choice for a wide range of applications, particularly where high image quality and low dispersion are required.
The lens is uncoated, meaning it does not have any anti-reflective coatings. While this can lead to higher levels of reflection at the lens surfaces, it can also be beneficial in certain applications where the user wants to control the amount of light entering the system.
According to the vendor's website, the lens is in stock, ensuring quick delivery for your optical project needs.
