L-BCX140 30 mm Dia. Double-Convex Lens; EFL=30mm Uncoated
The L-BCX140 is a 30 mm diameter double-convex lens, sourced from the renowned optical vendor, Ross Optical. This lens, with its spherical geometry, is designed for use in a wide range of optical applications.
The lens features a base shape of a circle, with a thickness of 2 mm at the edge and 10.3 mm at the center. The effective focal length (EFL) of this lens is 30 mm, making it a versatile choice for many optical systems. The first radius of curvature (R1) is 29.14 mm, while the second radius (R2) is -29.14 mm, indicating the double-convex nature of the lens.
The L-BCX140 is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. The lens is uncoated, offering a cost-effective solution for applications where anti-reflective coatings are not required.
This lens is designed to work with light of wavelength 587.6 nm. The item data does not specify any coatings on the lens, indicating that it is uncoated. This may make it more susceptible to surface reflections, but it also makes it more affordable and suitable for applications where such reflections are not a concern.
