SLB-50-350P 50.0 mm Dia. x 350.0 mm FL; Plano-Convex Lens Uncoated

The SLB-50-350P is a Plano-Convex lens with a diameter of 50.0 mm and a focal length of 350.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott material, a popular choice due to its excellent optical properties and versatility.

The lens geometry is characterized by its spherical shape, with a radius of curvature (R1) of 181.65 mm for the convex surface. The lens has an inner radius of 0 mm and an outer radius of 0 mm, indicating a uniform thickness across the lens. The edge thickness of the lens is 3 mm, while the center thickness is 4.7 mm, providing a balanced optical path.

The effective focal length (EFL) of the lens is 350.0 mm, which is the distance from the lens's principal point to the focal point where light rays converge. The back focal length (BFL) is 346.9 mm, which is the distance from the rear surface of the lens to the focal point.

This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While uncoated lenses can be more susceptible to surface reflections and scattering, they are often chosen for their cost-effectiveness and simplicity.

The lens is designed to operate at a wavelength of 546.1 nm, a common choice for general-purpose applications. It is important to note that the performance of the lens can vary depending on the wavelength and the angle of incidence of the light.
