48-324 25.0mm Dia. x -150 FL; UV-AR Coated; UV Plano-Concave Lens 250-425nm

This is a 25.0mm diameter UV Plano-Concave Lens, model 48-324, with a focal length of -150mm, sourced from Edmund Optics. The lens is designed for use within the UV spectrum, specifically between 250-425nm, making it ideal for applications such as UV imaging and spectroscopy.

The lens is made from fused silica (mal-1965), a material known for its high transparency in the UV range. It has a base shape of circular, with a thickness of 3.59mm at the edge and 2.5mm at the center. The inner and outer radii are both 0mm, indicating a uniform curvature.

The lens features UV-AR coating on both the front and back surfaces, providing excellent protection against UV light and reducing surface reflections. The coating follows the standard EDMM UV curve, ensuring high transmission and low absorption within the specified UV range.

The geometry of the lens is spherical, with a front surface radius (R1) of -68.76mm and a back focal length (BFL) of -151.71mm. This configuration results in a negative lens, suitable for use in a variety of optical systems where a diverging beam is required.
