48-046 12.0mm Dia. x -25 FL; Uncoated ; UV Plano-Concave Lens
The 48-046 12.0mm Dia. x -25 FL; Uncoated ; UV Plano-Concave Lens is a high-quality optical component sourced from Edmund Optics. This lens, with a diameter of 12.0mm, is designed for use in a wide range of optical applications, particularly those requiring a plano-concave lens.
The lens features a base shape of a circle, with a thickness of 3.52mm at the edge and 2.0mm at the center. It has an effective focal length (EFL) of -25, making it suitable for use in systems where a negative focal length is required. The lens's front radius of curvature (R1) is -11.46, and its back focal length (BFL) is -26.37.
The lens is made from fused silica (mal-1965), a material known for its excellent optical properties, including high transparency in the ultraviolet (UV) region. This makes the lens ideal for use in UV applications. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, this also means that it may be more susceptible to environmental factors such as dust and moisture.
The lens is designed to work with a wavelength of 587.6nm, which is in the visible light spectrum. It has a spherical shape, which is a common geometry for optical lenses due to its ease of manufacture and good optical performance.
