L-BCX105 22.4 mm Dia. Double-Convex Lens; EFL=80mm Uncoated
The L-BCX105 is a 22.4 mm diameter double-convex lens with an effective focal length (EFL) of 80mm, sourced from the renowned optical vendor, Ross Optical. This lens is a spherical type, specifically a bi-convex lens, which means it has two convex surfaces. The base shape is circular, ensuring consistent optical performance across the entire lens diameter.
The lens geometry is meticulously designed, with a thickness of 2mm at the edge and 3.5mm at the center. The inner and outer radii are 0, and the radii of curvature for the first and second surfaces are 82.09mm and -82.09mm respectively. This design allows for a high-quality, focused image.
The lens is made from n-BK7 Schott, a high-grade optical glass known for its excellent optical properties. It is specifically designed for use with a wavelength of 587.6nm, making it suitable for a wide range of optical applications.
Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections and increasing transmission, an uncoated lens can be advantageous in certain applications where specific reflection properties are required.
