L-BCX012 12 mm Dia. Double-Convex Lens; EFL=18mm Uncoated

The L-BCX012 is a 12 mm diameter double-convex lens, part of Ross Optical's extensive catalog of optical elements. This lens is characterized by its convex-convex base shape and circular geometry, making it suitable for a wide range of optical applications.

The lens has a center thickness of 3.5 mm and an edge thickness of 1.4 mm, providing a robust structure while maintaining a compact form factor. The effective focal length (EFL) of this lens is 18mm, making it a medium to long-range focal length lens. The radii of curvature for the first and second surfaces are 17.99mm and -17.99mm respectively, indicating a strongly converging lens.

The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This makes the lens suitable for use in applications where high image quality and low chromatic aberration are required. The lens is uncoated, meaning it does not have any additional layers to reduce surface reflections or protect the lens from environmental factors.

This lens is designed to work with light of wavelength 587.6 nm, which is in the yellow-green part of the visible light spectrum. It is a spherical lens, meaning it has a spherical surface, which is the simplest and most common type of lens surface.
