L-PCX051 65 mm Dia. Plano-Convex Lens; EFL=600mm Uncoated

The L-PCX051 is a Plano-Convex lens with a diameter of 65 mm, sourced from the renowned optical components vendor, Ross Optical. This lens is specifically designed for applications requiring a long effective focal length (EFL) of 600mm, making it suitable for use in scenarios demanding high magnification and narrow fields of view.

The lens geometry is characterized by its spherical shape, with a convex surface that has a radius of curvature of 310.08 mm. The lens's thickness varies from 4.8 mm at the edge to 6.5 mm at the center, providing structural rigidity while maintaining a manageable weight. The lens's base shape is circular, contributing to its versatility in various optical systems.

The L-PCX051 is made from N-BK7 Schott glass, a popular material in the optical industry due to its excellent optical properties and high Abbe number. This material ensures high transmission across a broad spectrum, making the lens suitable for use in a wide range of wavelengths, specifically around 587.6 nm.

Notably, this lens is uncoated, meaning it does not have any anti-reflective coatings. While this may result in a higher reflectance at the air-glass interfaces, it also means the lens is more cost-effective and easier to clean. However, for applications requiring higher light transmission or reduced ghosting and flaring, consider opting for a coated variant.
