45-026 25.0mm Dia. x -100 FL; Uncoated; Plano-Concave Lens
The 45-026 is a 25.0mm diameter Plano-Concave lens with a focal length of -100mm, sourced from the renowned optical component vendor, Edmund Optics. This lens is designed for use in a wide range of optical systems, particularly where a negative lens is required.
The lens is fabricated from the high-quality material, N-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This material is particularly suitable for applications in the visible spectrum, as demonstrated by its specified wavelength of 587.6nm.
The lens geometry features a concave surface with a radius of curvature of -51.68mm, and a thickness that varies from 4.85mm at the edge to 3.5mm at the center. The back focal length (BFL) is -102.31mm, and the effective focal length (EFL) is -100mm. The lens does not have any coating, which means it is uncoated, providing bare glass surfaces.
The lens is available in stock, as indicated by its weblink status. For more detailed information, users are encouraged to visit the vendor's website using the provided weblink.
