SLB-30-2500P 30.0 mm Dia. x 2500.0 mm FL; Plano-Convex Lens Uncoated
The SLB-30-2500P is a Plano-Convex lens with a diameter of 30.0 mm and a focal length of 2500.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott material, a high-quality glass known for its excellent optical properties.
The lens geometry is characterized by its spherical shape, with a center thickness of 2.1 mm and an edge thickness of 2 mm. The inner and outer radii are both 0 mm, indicating a uniform curvature. The back focal length (BFL) of the lens is 2498.6 mm, and its effective focal length (EFL) is 2500.0 mm. The radius of curvature (R1) is 1297.5 mm.
The lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This may result in higher reflective losses and lower transmission compared to coated lenses, but it also means that the lens is less susceptible to damage from environmental factors or handling.
