SLB-30B-250P 30.0 mm Dia. x 250.5 mm FL; Double-Convex Lens Uncoated
The SLB-30B-250P is a high-quality double-convex lens, sourced from the reputable optical vendor, OptoSigma. This lens, with a diameter of 30.0 mm and a focal length of 250.5 mm, is designed for use in a wide range of optical applications.
The lens is made from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The base shape of the lens is circular, and it features a spherical geometry, with a center thickness of 2.9 mm and an edge thickness of 2 mm. The effective focal length (EFL) of the lens is 250.5 mm, while the back focal length (BFL) is 249.5 mm.
The lens is uncoated, which means 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 lens material are desired. However, it's important to note that uncoated lenses can suffer from increased reflection, which may affect the overall performance of the optical system.
