SLB-05B-06P 5.0 mm Dia. x 6.4 mm FL; Double-Convex Lens Uncoated

The SLB-05B-06P is a 5.0 mm diameter double-convex lens with a focal length of 6.4 mm, sourced from OptoSigma. This lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and high homogeneity. The lens is uncoated, which means it does not have any additional layers to enhance its durability or alter its optical properties.

The lens has a base shape of a circle and a spherical geometry. The thickness at the edge is 1.5 mm, while the thickness at the center is 2.5 mm. The back focal length (BFL) is 5.6 mm, and the effective focal length (EFL) is 6.4 mm. The radii of curvature for the first and second surfaces are 6.23 mm and -6.23 mm, respectively. The lens does not have any inner or outer radius, indicating it is a simple lens without any additional features.

This lens is suitable for applications that require a simple, uncoated double-convex lens. Its high-quality optical glass and precise geometry make it a reliable choice for various optical systems. However, users should note that the lack of coating may make the lens more susceptible to environmental factors and may not provide the same level of optical performance as coated lenses.
