SLB-25.4-70P 25.4 mm Dia. x 70.0 mm FL; Plano-Convex Lens Uncoated
The SLB-25.4-70P is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 70.0 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 commonly used in optical applications due to its excellent optical properties.
The lens geometry is characterized by its spherical shape, with a center thickness of 4.2 mm and an edge thickness of 1.9 mm. The inner radius is 0 mm, and the outer radius is also 0 mm, indicating a plano surface on one side and a curved surface on the other. The back focal length (BFL) is 67.2 mm, and the effective focal length (EFL) is 70 mm.
The lens is uncoated, meaning it does not have any anti-reflective or other coatings. This may be suitable for applications where such coatings are not required or desirable. However, users should be aware that uncoated lenses can suffer from reflective losses, which may affect the performance of the optical system.
The lens is in stock and available for immediate purchase. More information, including technical specifications and purchasing details, can be found on the OptoSigma website using the provided weblink.
