SLB-25.4B-60P 25.4 mm Dia. x 60.8 mm FL; Double-Convex Lens Uncoated
The SLB-25.4B-60P is a high-quality double-convex lens offered by OptoSigma, a leading vendor in the optical industry. This lens, designed with a base shape of a circle, is constructed from n-bk7 schott material, a popular choice for its excellent optical properties.
The lens features a diameter of 25.4 mm and a thickness at the edge of 1.9 mm, ensuring durability while maintaining a sleek profile. The center thickness is 4.5 mm, providing a solid base for the lens. The effective focal length (EFL) of this lens is 60.8 mm, making it suitable for a wide range of optical applications.
The first radius of curvature (R1) is 62.28 mm, and the second radius (R2) is -62.28 mm, indicating the double-convex shape of the lens. The back focal length (BFL) is 59.2 mm, which is crucial for determining the position of the lens in an optical system.
This lens is uncoated, which means it does not have any anti-reflective or other coatings. While this may result in a higher risk of lens flare and lower light transmission, it also means the lens is more cost-effective and versatile, as it can be used in a wider range of wavelengths without the risk of coating damage.
