SLB-50.8-90P 50.8 mm Dia. x 90.0 mm FL; Plano-Convex Lens Uncoated

The SLB-50.8-90P is a Plano-Convex lens with a diameter of 50.8 mm and a focal length of 90.0 mm. This lens is sourced from OptoSigma, a renowned vendor known for its high-quality optical elements. The lens is made of n-bk7 schott material, a popular choice for its excellent optical properties.

The lens geometry is characterized by its base shape, which is circular, and its geometry specifications. The diameter of the lens is 50.8 mm, and it has an edge thickness of 3 mm and a center thickness of 10.3 mm. The effective focal length (EFL) is 90 mm, and the radius of curvature (R1) is 46.71 mm. The back focal length (BFL) is 83.2 mm, and both the inner and outer radii are 0 mm.

This lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be beneficial in certain applications where the natural properties of the material are desired. However, it's important to note that uncoated lenses can suffer from increased reflection, which may affect the overall performance in high-light applications.

The lens is designed to work with a wavelength of 546.1 nm, making it suitable for a wide range of applications in the visible light spectrum. The shape of the lens is spherical, which is a common choice for its ease of manufacturing and versatility in various optical systems.
