SLB-10B-20P 10.0 mm Dia. x 20.5 mm FL; Double-Convex Lens Uncoated

The SLB-10B-20P is a high-quality double-convex lens offered by OptoSigma, a leading vendor in the optical industry. This lens, with a base shape of a circle, is designed for use in a wide range of optical applications.

The lens has a diameter of 10.0 mm and a center thickness of 3.2 mm, with the edge thickness being 2.0 mm. The effective focal length (EFL) of this lens is 20.5 mm, making it suitable for applications that require a moderate focal length. The back focal length (BFL) is 19.5 mm, which is an important consideration when designing an optical system.

The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and high transmittance in the visible spectrum. The radii of curvature for the first and second surfaces are 20.76 mm and -20.76 mm, respectively, indicating a strongly converging lens.

The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in higher reflective losses, it also means that the lens is more versatile and can be used in a wider range of wavelengths.

The lens is currently in stock and can be purchased directly from the vendor's website. With its robust design and high-quality materials, the SLB-10B-20P is an excellent choice for anyone looking for a reliable and versatile double-convex lens.
