L-BCX139 29 mm Dia. Double-Convex Lens; EFL=82mm Uncoated

The L-BCX139 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 29 mm and a center thickness of 4.5 mm, with a slightly thinner edge thickness of 2 mm. The effective focal length (EFL) of this lens is 82 mm, making it suitable for a variety of optical applications.

The lens is made from the high-quality material n-BK7 Schott, a borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This material is particularly suitable for use in the visible spectrum, with a specified wavelength of 587.6 nm.

The L-BCX139 does not come with any coating, which means it is uncoated. While coatings can enhance the performance of a lens by reducing reflections, increasing transmission, or providing other benefits, an uncoated lens can be advantageous in certain applications where cost, simplicity, or specific optical characteristics are priorities.
