SLB-25B-100P 25.0 mm Dia. x 100.6 mm FL; Double-Convex Lens Uncoated

The SLB-25B-100P is a high-quality double-convex lens, sourced from the reputable optical vendor, OptoSigma. This lens, with a base shape of a circle, is designed for use in a wide range of optical applications, thanks to its precise geometry and material composition.

The lens has a diameter of 25.0 mm, making it suitable for use in compact optical systems. The edge thickness is 2.0 mm, while the center thickness is 3.5 mm, providing a robust structure that can withstand typical handling and usage. The effective focal length (EFL) of this lens is 100.6 mm, which is a common choice for many optical designs due to its versatility.

The curvature of the lens is defined by its first and second radii of curvature, R1 and R2, which are 103.8 mm and -103.8 mm respectively. These values indicate a symmetrical, double-convex lens, which is known for its ability to focus light efficiently. The back focal length (BFL) of this lens is 99.4 mm, a value that is crucial for determining the overall layout of an optical system.

The lens is made from n-BK7 Schott, a popular optical material known for its excellent optical properties and high transmission in the visible spectrum. The wavelength for which this lens is designed is 546.1 nm, a standard value in the optical industry.

Please note that this lens is uncoated. While uncoated lenses can be cost-effective, they may have lower transmission and are more susceptible to surface damage compared to coated lenses. Therefore, users should consider their specific application requirements when choosing between coated and uncoated lenses.
