L-BCX231 50.8 mm Dia. Double-Convex Lens; EFL=50.2mm Uncoated

The L-BCX231 is a high-quality double-convex lens offered by Ross Optical, a renowned vendor in the optical industry. This lens, with a diameter of 50.8 mm, is designed for use in a wide range of optical applications, thanks to its precise geometry and material properties.

The lens features a base shape of a circle, which is a common choice for many optical systems due to its symmetry and ease of alignment. The geometry of the lens includes a thickness of 3 mm at the edge and 17.27 mm at the center, providing a balanced profile for efficient light transmission. The effective focal length (EFL) of this lens is 50.2 mm, which is a critical parameter in determining the lens's focusing power.

The L-BCX231 lens is made from n-BK7 Schott, a high-grade optical material known for its excellent optical properties. This material ensures high transmission in the visible spectrum, making it suitable for applications that require clear and bright images.

The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. While coatings can provide benefits such as increased transmission, reduced reflection, and protection against environmental factors, an uncoated lens can be a cost-effective choice for applications where these benefits are not required.

This lens is designed to work with a wavelength of 587.6 nm, which is in the middle of the visible light spectrum. This makes it a versatile choice for applications that use white light or a broad spectrum of wavelengths.
