SLB-50.8-400P 50.8 mm Dia. x 400.0 mm FL; Plano-Convex Lens Uncoated

The SLB-50.8-400P is a Plano-Convex lens with a diameter of 50.8 mm and a focal length of 400.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott material, a high-quality glass known for its excellent optical properties.

The lens geometry is characterized by its spherical shape, with a center thickness of 4.5 mm and an edge thickness of 3 mm. The inner radius is 0 mm, and the outer radius is also 0 mm, indicating a plano surface on one side. The lens has a back focal length of 397 mm and a radius of curvature of 207.6 mm on the curved side.

The lens is uncoated, which means it does not have any anti-reflective or other coatings. This may result in higher reflective losses, but it also means that the lens can be used in a wider range of applications without the risk of coating-specific limitations.

The lens is designed to work with a wavelength of 546.1 nm, making it suitable for applications that use this specific wavelength. It is important to note that the lens's performance may vary depending on the application and the surrounding environmental conditions.
