LA4538 UV Fused Silica Plano-Convex Lens; Dia:2 in; f=250.9 mm; Uncoated

The LA4538 UV Fused Silica Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field. This lens is designed with a plano-convex base shape, featuring a circular geometry. The lens has a diameter of 2 inches (50.8 mm) and a center thickness of 5.8 mm, with the edge being slightly thinner at 3 mm.

The lens's effective focal length (EFL) is 250.9 mm, making it suitable for a wide range of optical applications. The radius of curvature (R1) is 115 mm, and the back focal length (BFL) is 246.9 mm. The lens's inner and outer radii are both 0, indicating a flat inner surface and a curved outer surface.

The LA4538 lens is made of UV Fused Silica, a material with the Material ID "uvfs mal- 1965". This material is known for its excellent transmission properties in the ultraviolet (UV) region, making this lens ideal for UV applications.

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, uncoated lenses can still provide high-quality performance, especially in applications where specific coatings are not required.

The lens's wavelength is 587.6 nm, which is in the visible light spectrum. This further expands its potential applications, including but not limited to, imaging, beam shaping, and laser systems.
