SLB-15B-25P 15.0 mm Dia. x 25.7 mm FL; Double-Convex Lens Uncoated
The SLB-15B-25P is a 15.0 mm diameter double-convex lens with a focal length of 25.7 mm, sourced from the reputable optical components manufacturer, OptoSigma. This lens is made of the high-quality material, n-bk7 schott, which is known for its excellent optical properties and durability.
The lens features a base shape of a circle, with a thickness of 2 mm at the edge and 4.2 mm at the center. The radii of curvature for the first and second surfaces are 25.95 mm and -25.95 mm respectively, contributing to its double-convex design. The back focal length of the lens is 24.3 mm, and it is designed to operate at a wavelength of 546.1 nm.
The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in a higher reflectivity at the air-glass interfaces, it also means that the lens is less susceptible to damage from environmental factors, making it suitable for applications where durability is a priority.
The lens is currently in stock and can be purchased directly from the OptoSigma website using the provided weblink. With its high-quality material, precise geometry, and robust design, the SLB-15B-25P is an excellent choice for a wide range of optical applications.
