L-PCX505 6.6 mm Dia. Plano-Convex Lens; EFL=40mm Uncoated

The L-PCX505 is a Plano-Convex lens with a 6.6 mm diameter, sourced from the renowned optical vendor, Ross Optical. This lens is specifically designed for use in spherical optical systems and features a base shape of a circle, ensuring versatility and wide applicability.

The lens has a center thickness of 1.8 mm and an edge thickness of 1.5 mm, providing a robust structure while maintaining a compact form factor. The effective focal length (EFL) of this lens is 40 mm, making it suitable for a wide range of optical applications.

The geometry of the L-PCX505 includes an inner radius of 0 mm and an outer radius of 0 mm, indicating a uniform curvature throughout the lens. The radius of curvature (R1) is 20.672 mm, and the back focal length (BFL) is 38.95 mm, providing precise control over the optical path.

The lens is made from the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including low dispersion and high transmission across the visible spectrum. The wavelength for this lens is 587.6 nm, which falls within the green region of the visible light spectrum.

Notably, this lens is uncoated, meaning it does not have any anti-reflective or other surface coatings. While this may result in a higher reflectance at the air-glass interface, it also ensures a more cost-effective solution for applications where such coatings are not required.
