L-BCX091 18 mm Dia. Double-Convex Lens; EFL=75mm Uncoated

The L-BCX091 is a double-convex lens with a diameter of 18 mm, sourced from the renowned optical component vendor, Ross Optical. 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 2.6 mm and an edge thickness of 1.6 mm, providing a robust structure while maintaining a compact form factor. The effective focal length (EFL) of this lens is 75 mm, making it a medium to long-range focal length lens. The radii of curvature for the first and second surfaces are 77.07 mm and -77.07 mm, respectively, indicating a symmetrical design that can minimize optical aberrations.

The L-BCX091 is made from N-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties and durability. The wavelength for this lens is 587.6 nm, which is within the visible light spectrum, making it suitable for applications such as imaging, metrology, and beam shaping.

Notably, this lens is uncoated, which means it does not have any anti-reflective or other surface coatings. While this may result in higher reflectivity at the lens surfaces, it can also provide greater design flexibility and cost-effectiveness in certain applications.
