48-319 25.0mm Dia. x -200 FL; Uncoated; UV Plano-Concave Lens

The 48-319 is a 25.0mm diameter Plano-Concave lens with a focal length of -200mm, sourced from the reputable optical vendor, Edmund Optics. This lens is designed for use in the ultraviolet (UV) spectrum, with a wavelength of 587.6nm, making it suitable for applications such as UV imaging and spectroscopy.

The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors. This can be advantageous in certain applications where minimal reflection or dispersion is required. However, it may be more susceptible to damage from dust, moisture, or other environmental factors.

The lens geometry includes a thickness of 3.32mm at the edge and 2.5mm at the center. The inner and outer radii are both 0, indicating a flat surface on one side and a curved surface on the other. The curvature of the concave surface is defined by a radius of -91.69mm.

The lens is made from fused silica, specifically the material type mal-1965. This material is known for its high transparency in the UV range, making it an ideal choice for UV applications.
