L-PCX178 25 mm Dia. Plano-Convex Lens; EFL=38mm Uncoated

The L-PCX178 is a Plano-Convex lens with a diameter of 25 mm, sourced from the renowned optical component vendor, Ross Optical. This lens is a spherical element, featuring a base shape that is circular, ensuring uniform light distribution.

The lens's geometry is meticulously designed, with a thickness at the edge of 1.1 mm and a center thickness of 5.6 mm. The Effective Focal Length (EFL) is 38 mm, making it suitable for a wide range of optical applications. The lens's radius of curvature (R1) is 19.6384 mm, and the back focal length (BFL) is 34.18 mm, contributing to its high-performance optical characteristics.

The L-PCX178 lens is made from the high-quality material N-BK7 Schott, a borosilicate glass known for its excellent optical properties, including low dispersion and high transmission in the visible spectrum. The material ID [n-bk7 schott] indicates that this lens is made from this specific glass type.

The lens is designed to work with a wavelength of 587.6 nm, which is the d-line of the sodium spectral lamp, often used as a reference wavelength in optical design. The lens's shape is spherical, and it does not come with any coating, as indicated by the empty 'coating' field in the item data.
