45-016 12.0mm Dia. x -24 FL; Uncoated; Plano-Concave Lens

The 45-016 is a 12.0mm diameter Plano-Concave lens with a focal length of -24 FL, sourced from the reputable optical vendor, Edmund Optics. This lens is a spherical element, featuring a base shape of a circle, designed for use in various optical applications.

The lens's geometry is meticulously crafted, with a thickness of 4.79mm at the edge and 3.5mm at the center, providing a balanced optical path. The inner and outer radii are both zero, indicating a uniform curvature throughout the lens. The back focal length (BFL) is -26.32, and the effective focal length (EFL) is -24, contributing to the lens's concave nature.

The lens is made from the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including high transmittance and low dispersion. The wavelength for this lens is 587.6nm, making it suitable for applications that require high precision and clarity in the yellow-green spectrum.

Notably, this lens is uncoated, offering users the flexibility to apply their preferred coating based on their specific application requirements. However, the lack of coating may result in reduced light transmission and increased susceptibility to environmental factors such as dust and moisture.
