L-BCX039 32.1 mm Dia. Double-Convex Lens; EFL=65.5mm Uncoated

The L-BCX039 is a high-quality double-convex lens, part of the extensive catalog offered by Ross Optical. This lens, with a diameter of 32.1 mm, is designed for use in a variety of optical applications, thanks to its robust construction and precise specifications.

The lens features a base shape of a circle, with an edge thickness of 5.5 mm and a center thickness of 9.4 mm. The effective focal length (EFL) of this lens is 65.5 mm, making it suitable for applications that require a longer focal length. The radii of curvature for the first and second surfaces are 66.06 mm and -66.06 mm, respectively, indicating a symmetrical design that can help minimize optical aberrations.

The L-BCX039 is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties and high transmittance in the visible spectrum. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors. However, uncoated lenses can be advantageous in certain applications where anti-reflection coatings may not be necessary or desirable.

This lens is designed to work with a wavelength of 587.6 nm, which is in the green part of the visible spectrum. It is spherical in shape, a common choice for many optical systems due to its simplicity and ease of manufacturing.
