SLB-40-120P 40.0 mm Dia. x 120.0 mm FL; Plano-Convex Lens Uncoated

The SLB-40-120P is a Plano-Convex lens with a diameter of 40.0 mm and a focal length of 120.0 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 center thickness of 5.3 mm and an edge thickness of 2 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 effective focal length (EFL) is 120.0 mm, and the back focal length (BFL) is 116.5 mm. The radius of curvature (R1) is 62.28 mm.

This lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. While this may result in higher reflective losses, it also means that the lens is more versatile and can be used in a wider range of applications without the risk of coating-specific limitations.

The lens is currently in stock and can be purchased directly from the vendor's website. It is suitable for use in various optical systems, including imaging systems, beam shaping applications, and laser systems.
