45-015 12.0mm Dia. x -12 FL; MgF2 Coated; Plano-Concave Lens 400-700nm
The 45-015 is a plano-concave lens with a diameter of 12.0mm, a focal length of -12mm, and a central thickness of 2.2mm. The lens is sourced from Edmund Optics, a leading manufacturer of optical components. It is designed for use in the visible spectrum, specifically between 400-700nm, making it suitable for a wide range of applications.
The lens is made from n-SF11 Schott, a high-index glass with excellent optical properties. The plano-concave geometry, characterized by a flat front surface and a curved back surface with a radius of curvature of -9.42mm, is designed to diverge light. This makes it ideal for use in applications where beam expansion is required.
The lens features a standard MgF2 coating on both the front and back surfaces. This coating, which has a characteristic transmission curve, is designed to reduce reflection and increase transmission in the visible spectrum. It is also scratch-resistant, ensuring the longevity and durability of the lens.
The lens has a clear aperture of 12.0mm and an effective focal length of -12mm. The back focal length is -13.23mm, and the lens has an inner radius of 0mm and an outer radius of 0mm. The edge thickness of the lens is 4.12mm.
