110-5245E 25.4 mm Dia. x 3000 mm FL; Uncoated; Plano-Convex Lens
The 110-5245E is a Plano-Convex lens, a type of spherical lens, sourced from EKSMA Optics. This lens boasts a diameter of 25.4 mm and an effective focal length (EFL) of 3000 mm. The lens is uncoated, offering a simple, cost-effective solution for applications that do not require specialized coatings.
The lens's geometry is defined by its edge thickness of 3 mm and center thickness of 3.1 mm. The inner radius is 0, and the outer radius is also 0, indicating a plano surface on one side and a curved surface on the other. The curvature of the curved surface is determined by a radius of 1254.7 mm.
This lens is made of CAF2 (MgF2), a material with a refractive index of 1.38 and a dispersion of 0.058. The wavelength for which these properties are specified is 2940 nm. This material is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum.
