112-5130E 12.7 mm Dia. x -250 mm FL; Uncoated; Plano-Concave Lens
The 112-5130E 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 features an uncoated surface.
The lens's geometry includes a thickness edge of 2 mm and a thickness center of 1.8 mm. The inner and outer radii are both 0 mm, and the radius of curvature (r1) is -104.6 mm. The lens is made from CAF2 (MgF2) material, specifically the Mal-1963 variant, and is designed to operate at a wavelength of 2940 nm.
This lens is a valuable addition to any optical system that requires a concave lens. Its compact size and high-quality construction make it suitable for a wide range of applications. The uncoated surface ensures high transmittance across the spectrum, making it an ideal choice for applications where minimal reflection is required.
