45-027 25.0mm Dia. x -100 FL; MgF2 Coated; Plano-Concave Lens 400-700nm
The 45-027 is a plano-concave lens with a diameter of 25.0mm, a focal length of -100, and a central thickness of 3.5mm. The edge thickness measures 4.85mm. This lens is sourced from Edmund Optics and is currently in stock.
The lens is made of BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and chemical durability. The lens features a spherical shape, with a radius of curvature of -51.68mm on the planar side and a back focal length of -102.31mm. The inner and outer radii are both zero, indicating a flat outer surface and a concave inner surface.
The lens is coated with MgF2, a standard coating that provides excellent optical performance in the 400-700nm wavelength range. This coating reduces reflection and increases transmission, enhancing the lens's overall performance. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from all angles.
This lens is a versatile optical component, suitable for a wide range of applications. Its compact size and high-quality coating make it an ideal choice for systems that require a plano-concave lens with excellent optical performance.
