SLB-50-2000P 50.0 mm Dia. x 2000.0 mm FL; Plano-Convex Lens Uncoated

The SLB-50-2000P is a Plano-Convex lens with a diameter of 50.0 mm and a focal length of 2000.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence.

The lens geometry is characterized by its spherical shape, with a radius of curvature (R1) of 1038 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 slightly higher at 3.3 mm. The back focal length (BFL) of the lens is 1997.8 mm.

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 wavelengths without the risk of coating damage. The lens is designed for use at a single wavelength of 546.1 nm.

The item data indicates that this lens is in stock, making it readily available for immediate use. The lens is a versatile optical component, suitable for a wide range of applications that require a long focal length and high-quality optical glass.
