L-BCX144 30 mm Dia. Double-Convex Lens; EFL=70mm Uncoated

The L-BCX144 is a 30 mm diameter Double-Convex lens, sourced from the renowned optical vendor, Ross Optical. This lens is a Spherical Lens of the Convex-Convex subtype, featuring a Circular base shape. The lens's geometry is meticulously designed, with a thickness edge of 2 mm and a thickness center of 5.2 mm, providing a robust structure for various optical applications.

The Effective Focal Length (EFL) of this lens is 70 mm, making it suitable for medium-range focus applications. The lens's first radius of curvature (R1) is 71.46 mm, while the second radius (R2) is -71.46 mm, indicating a symmetrically curved lens surface that ensures minimal optical aberrations. The lens does not have an inner or outer radius, suggesting a uniform curvature throughout.

The L-BCX144 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 across a wide spectrum. The lens is designed for use at a wavelength of 587.6 nm, making it suitable for applications in the visible light spectrum.

Notably, this lens is uncoated, meaning it does not have any anti-reflective or other surface coatings. While this may result in higher reflectivity, it also means the lens is more versatile and can be used in a wider range of applications without compatibility issues related to coatings.
