L-BCX724 22.4 mm Dia. Double-Convex Lens; EFL=200mm Uncoated

The L-BCX724 is a double-convex lens with a diameter of 22.4 mm, sourced from the renowned optical component vendor, Ross Optical. This lens is a spherical type, specifically designed with a convex-convex base shape, ensuring efficient light transmission and focusing.

The lens's geometry is meticulously crafted, with an edge thickness of 2 mm and a center thickness of 2.6 mm. The effective focal length (EFL) is 200 mm, making it suitable for applications requiring moderate to high magnification. The radii of curvature for the first and second surfaces are 206.28 mm and -206.28 mm, respectively, indicating a symmetrical design that reduces optical aberrations.

The L-BCX724 is made from the high-quality material n-BK7 Schott, a borosilicate glass known for its excellent optical properties, including high transparency and low dispersion. This material is ideal for applications in the visible spectrum, with a specified wavelength of 587.6 nm.

Notably, this lens is uncoated, meaning it does not have any anti-reflective or protective coatings. While this may result in a slightly lower transmission rate and increased susceptibility to environmental factors, it also means the lens can be easily customized with coatings to suit specific application requirements.
