LA4725 UV Fused Silica Plano-Convex Lens; Dia:1 in; f=75.3 mm Uncoated

The LA4725 UV Fused Silica Plano-Convex Lens is a high-quality optical component sourced from Thorlabs. This lens, with a diameter of 1 inch, is designed for use in ultraviolet (UV) applications, making it an ideal choice for projects that require precise manipulation of UV light.

The lens features a focal length of 75.3 mm, which is a crucial parameter in determining the lens's focusing power. The plano-convex design, where one side is flat and the other is curved, allows for efficient light transmission while minimizing spherical aberration.

The geometry of the lens includes a thickness of 2 mm at the edge and 4.4 mm at the center. The inner and outer radii are 0, indicating a circular base shape. The back focal length (BFL) is 72.2 mm, and the effective focal length (EFL) is 75.3 mm.

The lens is made of UV fused silica, a material known for its excellent transparency in the UV region. This material also has a low coefficient of thermal expansion, making it resistant to thermal shock.

The LA4725 lens does not come with any coating, which means it is uncoated. However, Thorlabs offers various coating options that can be added to enhance the lens's performance, such as anti-reflective coatings to reduce light loss due to reflection.
