LA4647-UV UV Fused Silica Plano-Convex Lens; Dia:0.5 in; f=20.1 mm ARC 245-400nm

The LA4647-UV is a UV Fused Silica Plano-Convex Lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens, with a diameter of 0.5 inches and a focal length of 20.1 mm, is designed to cater to the needs of applications that operate within the UV spectrum, specifically between 245-400 nm.

The lens geometry is characterized by a plano-convex shape, where one side is flat, and the other side is curved. The curvature of the lens is defined by a radius of 9.2 mm, which contributes to its focusing power. The lens has a central thickness of 4.3 mm and an edge thickness of 1.8 mm, providing structural rigidity and resistance to deformation.

The LA4647-UV lens is made from UV Fused Silica, a high-purity silica glass with excellent transmission properties in the UV range. This material is known for its low autofluorescence, making it ideal for applications that require high contrast and low background noise.

The lens features an Anti-Reflective (AR) coating on both surfaces, specifically designed for the UV range of 245-400 nm. This coating reduces surface reflections, thereby enhancing the transmission of light through the lens. The coating also provides protection against environmental contaminants and reduces the likelihood of surface damage during handling and operation.
