45-025 20.0mm Dia. x -50 FL; MgF2 Coated; Plano-Concave Lens 400-700nm
The 45-025 is a plano-concave lens with a diameter of 20.0mm, a focal length of -50, and a central thickness of 3.5mm. The lens is sourced from Edmund Optics, a leading vendor in the optical industry, and is currently in stock. It is designed for use within the wavelength range of 400-700nm, making it suitable for a wide range of optical applications.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. This material is widely used in the optical industry due to its superior optical properties. The lens features a spherical geometry, with a radius of curvature of -25.84mm on the concave surface. The lens has a clear aperture, with both the inner and outer radii being 0mm.
The 45-025 lens is coated with EDM MgF2 std curve on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, enhancing the performance of the lens. The coating is standard, providing a reliable and consistent performance.
