L-BCX212 47 mm Dia. Double-Convex Lens; EFL=1000mm Uncoated

The L-BCX212 is a 47 mm diameter Double-Convex (DCX) lens, part of the Spherical Lens (Convex-Convex) category, offered by Ross Optical. This lens is characterized by its base shape being circular, with a circular geometry that includes a thickness edge of 2 mm and a thickness center of 2.5 mm. The Effective Focal Length (EFL) of this lens is an impressive 1000mm, making it suitable for applications requiring significant magnification or focusing power.

The lens's inner and outer radii are 0, and its radii of curvature (R1 and R2) are +1033.17 mm and -1033.17 mm, respectively. These specifications indicate a symmetrical, double-convex lens, which is known for its ability to converge light rays efficiently. The lens is made from the material n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties, including high transparency and low dispersion.

The lens is designed to operate at a wavelength of 587.6 nm, which is within the visible light spectrum. It does not come with any coating, as indicated in the item data. However, users can consider various coating options to enhance the lens's performance, such as anti-reflective coatings to reduce light loss due to reflection or hard coatings to increase the lens's durability.
