SLB-80-400P 80.0 mm Dia. x 400.0 mm FL; Plano-Convex Lens Uncoated

The SLB-80-400P is a Plano-Convex lens with a diameter of 80.0 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 popular choice due to its excellent optical properties and versatility.

The lens geometry is characterized by a thickness of 3.0 mm at the edge and 6.9 mm at the center. The inner radius is 0 mm, and the outer radius is also 0 mm, indicating a flat surface on one side and a curved surface on the other. The effective focal length (EFL) is 400.0 mm, and the back focal length (BFL) is 395.5 mm. The radius of curvature (R1) is 207.6 mm.

This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While this may result in a lower transmission rate and increased susceptibility to environmental factors, it also means that the lens can be easily integrated into various systems without worrying about compatibility issues with different coating types.

The lens data suggests that it is suitable for applications that require a long focal length and a large diameter. This could include imaging systems, beam shaping, or other applications where a precise, undistorted image is required over a large area.
