48-325 25.0mm Dia. x -200 FL; UV-AR Coated; UV Plano-Concave Lens 250-425nm

The 48-325 is a UV-AR coated, UV plano-concave lens with a diameter of 25.0mm and a focal length of -200mm. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components. The lens is designed for use within the UV spectrum, specifically between 250-425nm, making it ideal for applications such as UV imaging, spectroscopy, and other UV-based research or industrial processes.

The lens is constructed from fused silica (mal-1965), a material known for its excellent transparency in the UV range. The plano-concave geometry of the lens, where one surface is flat and the other is curved, allows for precise control over the light path, making it suitable for use in optical systems that require careful manipulation of light.

The lens features a standard UV coating on both the front and back surfaces, providing enhanced protection against UV radiation and improving the overall durability of the component. This coating is designed to the standard UV curve, ensuring consistent performance across a wide range of UV wavelengths.

The geometry of the lens includes a thickness of 3.32mm at the edge and 2.5mm at the center. The inner and outer radii are both 0mm, indicating a simple, straightforward design that is easy to integrate into existing optical systems.
