The LA4246 UV Fused Silica Plano-Convex Lens is a high-quality optical component designed for use in a wide range of applications. This lens, sourced from the reputable vendor Thorlabs, boasts a diameter of 75 mm and a focal length of 501.8 mm, making it a versatile choice for many optical systems.
The lens is made from UV Fused Silica, a material known for its excellent transmission properties across a broad spectrum, including the ultraviolet range. This makes the LA4246 particularly suitable for applications that require high transmittance in the UV region.
The lens features a plano-convex geometry, with a spherical surface and a flat base. The radius of curvature of the spherical surface is 230 mm, and the lens has a center thickness of 3 mm, which increases to 3 mm at the edge. The effective focal length (EFL) of the lens is 501.8 mm, and the back focal length (BFL) is 497.6 mm.
The LA4246 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 bare substrate is preferred. However, for applications that require reduced surface reflections or specific wavelength performance, coatings can be applied.
