SLB-50-90P 50.0 mm Dia. x 90.0 mm FL; Plano-Convex Lens Uncoated

The SLB-50-90P is a Plano-Convex lens with a diameter of 50.0 mm and a focal length of 90.0 mm, sourced from the reputable optical components manufacturer, OptoSigma. This lens is made of the high-quality material, n-BK7 Schott, which is renowned for its excellent optical properties, making it a popular choice for various applications.

The lens geometry is characterized by its spherical shape, with a center thickness of 10.3 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 and a curved surface on the other. The effective focal length (EFL) is 90.0 mm, and the back focal length (BFL) is 83.2 mm. The radius of curvature (R1) is 46.71 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.
