LA4130 UV Fused Silica Plano-Convex Lens; Dia:0.5 in; f=40.1 mm Uncoated

The LA4130 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 features a focal length of 40.1 mm, making it suitable for use in systems where a longer focal length is required.

The lens is made of UV Fused Silica, a material known for its excellent optical properties, including high transparency across a wide range of wavelengths. This makes the LA4130 particularly suitable for use in ultraviolet (UV) applications. The material also has a low coefficient of thermal expansion, making it resistant to thermal shock and suitable for use in environments with varying temperatures.

The lens has a spherical shape, with a plano-convex design. This means that one side of the lens is flat (plano), while the other side is curved (convex). The curvature of the lens is defined by a radius of 18.4 mm. This curvature, combined with the lens's thickness, results in a back focal length of 38.1 mm.

The LA4130 is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be advantageous in certain applications where a specific coating is not required or desired. However, it's important to note that uncoated lenses can be more susceptible to surface damage and may not perform as well in high-intensity light applications.
