This LA4078-UV UV Fused Silica Plano-Convex Lens, sourced from Thorlabs, is a high-quality optical component designed for use in a wide range of applications. The lens features a plano-convex design, which means one side is flat (plano) and the other side is curved (convex). This design is particularly useful in focusing or collimating light beams.
The lens has a diameter of 2 inches (50.8 mm) and a focal length of 75.3 mm. The focal length, denoted as 'f', is the distance between the lens and the point where the light rays converge or diverge. This focal length makes the lens suitable for applications that require moderate magnification.
The lens is made of UV Fused Silica, a material known for its excellent optical properties and high damage threshold. It is particularly suitable for use in the ultraviolet region of the spectrum, as indicated by its ARC 245-400nm coating. This coating enhances the lens's performance by reducing reflection and increasing transmission in the specified wavelength range.
The lens has a central thickness of 14.2 mm and an edge thickness of 3 mm, providing structural rigidity and minimizing optical distortions. The lens's geometry, including its inner and outer radii, is designed to optimize its optical performance.
