SLB-05B-20P 5.0 mm Dia. x 20.2 mm FL; Double-Convex Lens Uncoated

The SLB-05B-20P is a high-quality spherical lens, specifically designed with a double-convex shape, sourced from the reputable vendor OptoSigma. This lens boasts a 5.0 mm diameter and a focal length of 20.2 mm, making it suitable for a wide range of optical applications.

The lens is fabricated from the renowned material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including low dispersion and high homogeneity. This material ensures reliable and precise light transmission, making the lens an ideal choice for applications that demand high-fidelity imaging or light manipulation.

The lens geometry features a thickness of 1.1 mm at the edge and 1.4 mm at the center, providing a robust structure while maintaining a sleek profile. The double-convex shape, characterized by radii of curvature of 20.76 mm for both surfaces, offers a high refractive power, making it suitable for focusing or collimating light beams.

The lens is uncoated, offering a bare, unaltered glass surface. While this may result in a slightly lower transmission rate compared to coated lenses, it ensures a cost-effective solution without compromising the lens's optical performance.

The SLB-05B-20P is currently in stock and available for immediate purchase through the OptoSigma website. With its superior optical properties, robust construction, and versatile design, this lens is an excellent choice for various optical systems and setups.
