The 45-699 is a 6.0mm diameter Plano-Concave lens with a focal length of -18 FL, sourced from the reputable optical vendor, Edmund Optics. This lens is designed for use in ultraviolet (UV) applications, making it suitable for a wide range of scientific and industrial uses.
The lens is fabricated from fused silica, a material known for its high transparency in the UV region, and its resistance to thermal shock and chemical etching. The base shape of the lens is circular, and it features a spherical geometry, with a center thickness of 2mm and an edge thickness of 2.45mm. The inner and outer radii are both 0, indicating a uniform curvature throughout the lens.
The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, this also means that it is less susceptible to damage from environmental factors and handling. The lens is designed to operate at a wavelength of 587.6nm, which is in the visible light spectrum.
