L-BCX096 18 mm Dia. Double-Convex Lens; EFL=250mm Uncoated

The L-BCX096 is a spherical lens with a base shape of a circle, sourced from the renowned optical vendor, Ross Optical. This lens is a double-convex type, characterized by its convex-convex geometry, making it suitable for a wide range of optical applications.

The lens has a diameter of 18 mm and a thickness at the edge of 1.5 mm, while the center thickness is 1.8 mm. The effective focal length (EFL) of this lens is 250 mm. The first radius of curvature (R1) is 258.09 mm, and the second radius of curvature (R2) is -258.09 mm, indicating the double-convex nature of the lens. The inner and outer radii are both 0, suggesting a symmetrical lens design.

The lens is made of n-bk7 Schott material, a common and reliable option in the optical industry. It is designed to work with a wavelength of 587.6 nm. The lens's shape is spherical, a common choice for many optical systems due to its ease of manufacturing and versatility.

Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their performance by reducing reflections, increasing transmission, or providing other desirable optical properties. However, this lens is in its bare form, offering a different set of advantages, such as cost-effectiveness and simplicity.
