L-BCX258 75 mm Dia. Double-Convex Lens; EFL=250mm Uncoated
The L-BCX258 is a high-quality double-convex lens, boasting a 75 mm diameter and a focal length of 250 mm. This lens is sourced from the renowned optical vendor, Ross Optical, and is available for purchase on their website. The lens is uncoated, which means it does not have any additional layers to protect the surface or modify its optical properties.
The lens is spherical in shape, with a base shape of a circle. The geometry of the lens is meticulously crafted, with an edge thickness of 2.9 mm and a center thickness of 8.4 mm. The inner and outer radii are 0, indicating a symmetrical design. The radius of curvature for the first and second surfaces are 256.96 mm and -256.96 mm respectively, which contributes to its double-convex nature.
The lens is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties. It is designed to work with a wavelength of 587.6 nm. The lens is in stock, as indicated by the "weblink status" field, making it readily available for immediate use.
