L-PCX258 40 mm Dia. Plano-Convex Lens; EFL=70mm Uncoated
The L-PCX258 is a 40 mm diameter Plano-Convex lens, sourced from the renowned optical component vendor, Ross Optical. This lens is specifically designed for use in a wide range of optical applications, boasting an effective focal length (EFL) of 70mm and a shape defined by a spherical geometry.
The lens's base shape is circular, and it features a planar surface on one side and a convex surface on the other. The thickness at the edge of the lens is 1.9mm, while the center thickness measures 7.9mm, providing a solid structure suitable for various optical systems. The lens's inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature throughout.
The L-PCX258 is made from the high-quality material N-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This material is particularly suitable for applications that require high precision and durability.
The lens is designed to work with a wavelength of 587.6nm, making it suitable for use in systems that operate within the visible light spectrum. The lens does not come with any coating, which means it is uncoated. However, users can opt for additional coatings based on their specific application requirements.
