LA4158 UV Fused Silica Plano-Convex Lens; Dia:1 in; f=250.9 mm Uncoated

The LA4158 UV Fused Silica Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical equipment. This lens, with a diameter of 1 inch, is designed for use in ultraviolet (UV) applications, making it an ideal choice for researchers and engineers working in this spectrum.

The lens is spherical in shape, specifically a plano-convex lens, which means it has a flat surface and a curved surface. The curvature of the lens is defined by a radius of 115 mm, which contributes to its focal length of 250.9 mm. This focal length, denoted as 'efl', is a critical parameter in lens selection, as it determines the distance at which the lens will focus light.

The lens's geometry includes a thickness of 2 mm at the edge and 2.7 mm at the center. This slight curvature at the center allows for efficient light bending, a key function of lenses. The lens's base shape is circular, ensuring uniform light distribution and minimal distortion.

The LA4158 lens is made of UV Fused Silica, a material with a high transmission rate in the UV range. This material is identified as 'uvfs mal- 1965' in the item data. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, its inherent material properties make it suitable for many UV applications.
