LA4647 UV Fused Silica Plano-Convex Lens; Dia:0.5 in; f=20.1 mm Uncoated

The LA4647 UV Fused Silica Plano-Convex Lens is a high-quality optical component sourced from Thorlabs. This lens, with a diameter of 0.5 inches, is designed for use in a variety of applications that require precise optical control. The lens's plano-convex shape, where one side is flat and the other is curved, allows for efficient light gathering and focusing.

The lens is made from UV Fused Silica, a material known for its excellent optical properties, including high transparency across a wide range of wavelengths. This particular lens is designed for use with a wavelength of 587.6 nm, making it suitable for applications that require precise control of visible light.

The geometry of the lens is carefully controlled. It has an outer diameter of 12.7 mm, with a center thickness of 4.3 mm and an edge thickness of 1.8 mm. The lens's effective focal length (EFL) is 20.1 mm, which determines the distance at which it focuses light. The radius of curvature of the curved surface is 9.2 mm, and the back focal length (BFL) is 17.1 mm.

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, this does not affect its performance in many applications. The lens's high-quality construction and precise specifications make it a reliable choice for a wide range of optical systems.
