L-BCX023 19.5 mm Dia. Double-Convex Lens; EFL=35mm Uncoated

The L-BCX023 is a spherical lens with a base shape of circular and a double-convex design, sourced from the reputable vendor Ross Optical. This lens boasts a diameter of 19.5 mm and a center thickness of 4.7 mm, with a uniform edge thickness of 2 mm, contributing to its robust construction.

The lens has an effective focal length (EFL) of 35 mm, making it suitable for a wide range of optical applications. The radii of curvature for the first and second surfaces are 35.36 mm and -35.36 mm respectively, indicating a symmetrical design that can minimize optical aberrations.

The L-BCX023 is crafted 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 lens is designed to operate at a wavelength of 587.6 nm, which is within the visible light spectrum.

Notably, this lens does not come with any coating, which means it is uncoated. While coatings can enhance the performance of lenses by reducing reflections, increasing transmittance, or adding protective layers, an uncoated lens can be advantageous in certain applications where cost, simplicity, or specific optical characteristics are priorities.
