112-0125E 12.7 mm Dia. x -250 mm FL; Uncoated; Plano-Concave Lens
The 112-0125E is a plano-concave lens with a diameter of 12.7 mm and a focal length of -250 mm, sourced from EKSMA Optics. This lens is a spherical type, designed with a base shape of a circle, and is uncoated. The lens's edge thickness measures 3.5 mm, while the center thickness is slightly less at 3.3 mm.
The lens is made from the material n-bk7 schott, a popular choice for optical elements due to its excellent optical properties. The wavelength for this lens is 546 nm. The lens's geometry is such that it has an inner radius of 0 mm and an outer radius of 0 mm, indicating a plano surface on one side and a concave surface on the other.
This lens is a versatile component, suitable for a wide range of applications where a negative focal length and a concave surface are required. The uncoated version offers a cost-effective solution, although coated versions are also available for applications where surface reflections need to be minimized.
