LA4966 UV Fused Silica Plano-Convex Lens; Dia:6 mm; f=30.1 mm Uncoated

The LA4966 UV Fused Silica Plano-Convex Lens is a high-quality optical component sourced from Thorlabs. This lens, with a diameter of 6 mm, is designed for use in ultraviolet (UV) applications, making it ideal for a wide range of scientific and industrial uses.

The lens features a plano-convex shape, meaning one side is flat (plano) and the other is curved (convex). This design allows for efficient light transmission and focusing. The base shape of the lens is circular, ensuring uniform light distribution.

The geometry of the LA4966 includes a thickness of 1.5 mm at the edge and 2 mm at the center. The effective focal length (EFL) is 20 mm, and the radius of curvature (R1) is 13.8 mm. The back focal length (BFL) is 19.3 mm, and both the inner and outer radii are 0 mm, indicating a flat surface on the non-curved side.

The lens is made from UV fused silica, a material known for its excellent transparency in the UV range. This makes the LA4966 particularly suitable for applications that require high UV transmission.

The wavelength for this lens is 587.6 nm, which falls within the visible light spectrum. However, due to its UV fused silica material, it is still effective in UV applications.

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. This can be beneficial in certain applications where a specific coating is not required or desired.
